IMPORTANT SAFETY INSTRUCTIONS
Air-cooled Generators
SAVE THESE INSTRUCTIONS The manufacturer suggests that these rules for safe operation
be copied and posted near the units installation site. Safety should be stressed to all operators and potential operators of this equipment.
WARNING:
The engine exhaust from this product
contains chemicals known to the state
of California to cause cancer, birth
defects or other reproductive harm.
WARNING:
This product contains or emits chemicals
known to the state of California to cause
cancer, birth defects or other reproductive harm.
Study these SAFETY RULES carefully before installing, operating or servicing this equipment. Become
familiar with this Owners Manual and with the
unit. The generator can operate safely, efficiently and
reliably only if it is properly installed, operated and
maintained. Many accidents are caused by failing to
follow simple and fundamental rules or precautions.
The manufacturer cannot anticipate every possible
circumstance that might involve a hazard. The warnings in this manual, and on tags and decals affixed
to the unit are, therefore, not all-inclusive. If using
a procedure, work method or operating technique
the manufacturer does not specifically recommend,
ensure that it is safe for others. Also make sure the
procedure, work method or operating technique utilized does not render the generator unsafe.
DANGER

Parts
during operation. Exercise care near running
generators.
GENERAL HAZARDS
For safety reasons, the manufacturer recommends
that the installation, initial start-up and maintenance of this equipment is carried out by an
Authorized Dealer.
The engine exhaust fumes contain carbon monoxide, which can be DEADLY. This dangerous gas, if
breathed in sufficient concentrations, can cause
unconsciousness or even death. This exhaust
system must be installed properly, in strict compliance with applicable codes and standards.
Following installation, do nothing that might render the system unsafe or in noncompliance with
such codes and standards.
Keep hands, feet, clothing, etc., away from drive
belts, fans, and other moving or hot parts. Never
remove any drive belt or fan guard while the unit
is operating.
Adequate, unobstructed flow of cooling and ventilating air is critical to correct generator operation.
Do not alter the installation or permit even partial
blockage of ventilation provisions, as this can seriously affect safe operation of the generator. The
generator MUST be installed outdoors.
When working on this equipment, remain alert
at all times. Never work on the equipment when
physically or mentally fatigued.
Inspect the generator regularly, and contact the
nearest Authorized Dealer for parts needing repair
or replacement.
Before performing any maintenance on the generator, disconnect its battery cables to prevent
accidental start up. Disconnect the cable from the
battery post indicated by a NEGATIVE, NEG or
() first, then remove the POSITIVE, POS or (+)
cable. When reconnecting the cables, connect the
POSITIVE cable first, the NEGATIVE cable last.
Never use the generator or any of its parts as a
step. Stepping on the unit can stress and break
parts, and may result in dangerous operating conditions from leaking exhaust gases, fuel leakage,
oil leakage, etc.
IMPORTANT SAFETY INSTRUCTIONS
Air-cooled Generators
ELECTRICAL HAZARDS
All generators covered by this manual produce
dangerous electrical voltages and can cause fatal
electrical shock. Utility power delivers extremely
high and dangerous voltages to the transfer switch
as does the standby generator when it is in operation. Avoid contact with bare wires, terminals,
connections, etc., while the unit is running. Ensure
all appropriate covers, guards and barriers are in
place, secured and/or locked before operating the
generator. If work must be done around an operating unit, stand on an insulated, dry surface to
reduce shock hazard.
Do not handle any kind of electrical device while
standing in water, while barefoot, or while hands or
feet are wet. DANGEROUS ELECTRICAL SHOCK
MAY RESULT.
The National Electrical Code (NEC) requires the
frame and external electrically conductive parts of
the generator to be connected to an approved earth
ground. Local electrical codes also may require
proper grounding of the generator electrical system.
After installing this home standby electrical system, the generator may crank and start at any
time without warning. When this occurs, load circuits are transferred to the STANDBY (generator)
power source. To prevent possible injury if such a
start and transfer occur, always set the generators
AUTO/OFF/MANUAL switch to its OFF position
before working on equipment and remove the 15A
fuse from the generator control panel.
In case of accident caused by electric shock, immediately shut down the source of electrical power. If
this is not possible, attempt to free the victim from
the live conductor. AVOID DIRECT CONTACT WITH
THE VICTIM. Use a nonconducting implement,
such as a dry rope or board, to free the victim from
the live conductor. If the victim is unconscious,
apply first aid and get immediate medical help.
Never wear jewelry when working on this equipment. Jewelry can conduct electricity resulting in
electric shock, or may get caught in moving components causing injury.
FIRE HAZARDS
For fire safety, the generator must be installed and
maintained properly. Installation must always
comply with applicable codes, standards, laws
and regulations. Adhere strictly to local, state
and national electrical and building codes. Comply
with regulations the Occupational Safety and
Health Administration (OSHA) has established.
Also, ensure that the generator is installed in
accordance with the manufacturers instructions
and recommendations. Following proper installation, do nothing that might alter a safe installation
and render the unit in noncompliance with the
aforementioned codes, standards, laws and regulations.
Keep a fire extinguisher near the generator at all
times. Extinguishers rated ABC by the National
Fire Protection Association are appropriate for
use on the standby electric system. Keep the extinguisher properly charged and be familiar with its
use. Consult the local fire department with any
questions pertaining to fire extinguishers.
EXPLOSION HAZARDS
Do not smoke around the generator. Wipe up any
fuel or oil spills immediately. Ensure that no combustible materials are left in the generator compartment, or on or near the generator, as FIRE or
EXPLOSION may result. Keep the area surrounding the generator clean and free from debris.
Gaseous fluids such as natural gas and liquid propane (LP) gas are extremely EXPLOSIVE. Install
the fuel supply system according to applicable
fuel-gas codes. Before placing the home standby
electric system into service, fuel system lines must
be properly purged and leak tested according to
applicable code. After installation, inspect the fuel
system periodically for leaks. No leakage is permitted.

strictly with applicable codes, standards and regulations.
1.1
UNPACKING/INSPECTION
After unpacking, carefully inspect the contents for
damage.
This standby generator set is ready for installation with a factory supplied and pre-mounted base
pad and has a weather protective enclosure that is
intended for outdoor installation only.
This UL listed standby generator set is packaged
with an automatic transfer switch with built in
load center. The combination transfer switch and
load center is pre-wired with a two foot and 30 foot
conduit. Circuit breakers for emergency circuit
connections are included (if equipped).
This UL listed, 2-pole switch is rated at 100 AC
amperes at 250 volts maximum. This transfer
switch is for indoor use only (if equipped).
this generator is used to power electrical load
Ifcircuits
normally powered by a utility power
source, it is required by code to install a transfer
switch. The transfer switch must effectively isolate
the electrical system from the utility distribution
system when the generator is operating (NEC 700,
701 & 702). Failure to isolate an electrical system
by such means will result in damage to the generator and also may result in injury or death to
utility power workers due to backfeed of electrical
energy.
If any loss or damage is noted at time of delivery, have
the person(s) making the delivery note all damage
on the freight bill or affix their signature under the
consignor's memo of loss or damage.
If a loss or damage is noted after delivery, separate
the damaged materials and contact the carrier for
claim procedures.
Concealed damage is understood to mean damage
to the contents of a package that is not in evidence at
the time of delivery, but is discovered later.
1.2
PROTECTION SYSTEMS
Unlike an automobile engine, the generator may have
to run for long periods of time with no operator present to monitor engine conditions. For that reason, the
engine is equipped with the following systems that
protect it against potentially damaging conditions:
1. Low Oil Pressure Sensor
2. High Temperature Sensor
3. Overcrank
4
4. Overspeed
5. RPM Sensor
6. Low Battery
There are LED readouts on the control panel to notify
personnel that one of these faults has occurred.
There is also a System Set LED that is lit when all
of the conditions described in section "System Set
LED" are true. (See the "Protection Systems" section
for details.)
1.3
NEC REQUIREMENT FOR ARC
FAULT CIRCUIT INTERRUPTION
BREAKER FOR BEDROOMS
In 2001, the National Electric Code (NEC) introduced a requirement for new construction. This new
requirement indicates the need for Arc Fault Circuit
Interrupters to be used to protect the complete
branch circuit that feeds a dwelling bedroom. The
actual NEC requirement is indicated below.
1.3.1 SECTION 210.12 ARC FAULT CIRCUIT
INTERRUPTER PROTECTION
1. Definition: An arc fault circuit interrupter is a
device intended to provide protection from the
effects of arc faults by recognizing characteristics
unique to arcing and by functioning to de-energize the circuit when an arc fault is detected.
2. Dwelling Unit Bedrooms: All branch circuits that
supply 125 volt, single-phase, 15 and 20 ampere
outlets installed in dwelling unit bedrooms shall
be protected by an arc fault circuit interrupter
listed to provide protection of the entire branch
circuit.
Section 210.12 requires that AFCI protection be
provided on branch circuits that supply outlets
(receptacle, lighting, etc.) in dwelling bedrooms. The
requirement is limited to 15 and 20 ampere, 125
volt circuits. There is no prohibition against providing AFCI protection on other circuits or in locations
other than bedrooms. Because circuits are often
shared between a bedroom and other areas such as
closets and hallways, providing AFCI protection on
the complete circuit would comply with 210.12.
If during the installation of the home standby system
the decision is made to provide back up power to a
bedroom branch circuit, then the circuit breaker in
the transfer switch should be replaced with an Arc
Fault Circuit Interrupter.
It is most important that breakers only be switched
like for like. For instance, if replacing a 15A breaker,
it MUST be replaced with a 15A AFCI breaker.
Likewise, a 20A breaker MUST be replaced with a
20A AFCI.
These AFCI breakers are available at the nearest
hardware store.

SYSTEM SET LED
The System Set LED is lit when all of the following
conditions are true:
1. The AUTO/OFF/MANUAL switch is set to the
AUTO position.
2. The utility voltage being supplied to the unit is
being sensed by the PCB. If the utility sense voltage is not connected to the unit or if it is below
approximately 150-160 volts AC, then the system
set light will flash rapidly. This indicates that if
the AUTO/OFF/ MANUAL switch is placed in the
Auto position, the generator will start.
3. No alarms are present, for example, low oil pressure, high temperature, etc.
1.7
Special considerations should be given when installing the unit where local conditions include flooding,
tornados, hurricanes, earthquakes and unstable
ground for the flexibility and strength of piping and
their connections.
Use an approved pipe sealant or joint compound on
all threaded fitting.
All installed gaseous fuel piping must be purged and
leak tested prior to initial start-up in accordance with
local codes, standards and regulations.
1.8
Unit
FUEL REQUIREMENTS
AND RECOMMENDATIONS
With LP gas, use only the vapor withdrawal system. This type of system uses the vapors formed
above the liquid fuel in the storage tank.
The engine has been fitted with a fuel carburetion
system that meets the specifications of the 1997
California Air Resources Board for tamper-proof dual
fuel systems. The unit will run on natural gas or LP
gas, but it has been factory set to run on natural gas.
Should the primary fuel need to be changed to LP
gas, the fuel system needs to be reconfigured. See the
Reconfiguring the Fuel System section for instructions on reconfiguration of the fuel system.
Recommended fuels should have a Btu content of at
least 1,000 Btus per cubic foot for natural gas; or at
least 2,520 Btus per cubic foot for LP gas. Ask the
fuel supplier for the Btu content of the fuel.
Required fuel pressure for natural gas is 5 inches
to 7 inches water column (0.18 to 0.25 psi); and
for liquid propane, 10 inches to 12 inches of water
column (0.36 to 0.43 psi). The primary regulator
for the propane supply is NOT INCLUDED with the
generator.
NOTE:
All pipe sizing, construction and layout must comply with NFPA 54 for natural gas applications and
NFPA 58 for liquid propane applications. Once the
generator is installed, verify that the fuel pressure
NEVER drops below four (4) inches water column
for natural gas or 10 inches water column for liquid propane.
Prior to installation of the generator, the installer
should consult local fuel suppliers or the fire marshall to check codes and regulations for proper
installation. Local codes will mandate correct routing
of gaseous fuel line piping around gardens, shrubs
and other landscaping to prevent any damage.

DANGER
fuels such as natural gas and liquid
Gaseous
propane (LP) gas are highly explosive. Even the
slightest spark can ignite such fuels and cause
an explosion. No leakage of fuel is permitted.
Natural gas, which is lighter than air, tends to
collect in high areas. LP gas is heavier than air
and tends to settle in low areas.
NOTE:
A minimum of one approved manual shut-off valve
must be installed in the gaseous fuel supply line.
The valve must be easily accessible. Local codes
determine the proper location.

RECONFIGURING THE
FUEL SYSTEM
NOTE:
Use an approved pipe sealant or joint compound
on all threaded fittings to reduce the possibility
of leakage.
1.9.1 7 KW, 410CC ENGINE
To reconfigure the fuel system from NG to LP, follow
these steps (Figure 1.4):
NOTE:
The primary regulator for the propane supply is
NOT INCLUDED with the generator. A fuel pressure of 10 to 12 inches of water column (0.36 to

prevent possible injury that might be caused
by such sudden starts, always set the switch to
OFF and remove the fuses before working on or
around the generator or transfer switch. Then,
place a DO NOT OPERATE tag on the generator panel and on the transfer switch.
3.1.4 CHOKE OPERATION
1. 990 engines have an electric choke in the air box
that is automatically controlled by the electronic
control board.
2. 530 engines have an electric choke on the divider
panel air inlet hose that is automatically controlled by the electronic control board.
3. 410 engines have a choke behind the air box that
is automatically controlled by the electronic control board.
SEQUENCE OF AUTOMATIC
OPERATION
The generators control panel houses a control logic
circuit board. This board constantly monitors utility power source voltage. Should that voltage drop
below a preset level, circuit board action will signal
the engine to crank and start. After the engine starts,
the circuit board signals the transfer switch to activate and connect load circuits to the standby power
supply (load terminal lugs T1/T2 connect to terminal
lugs E1/E2). Refer to the Electrical Data section.
The generator must run at 50 Hz or greater for the
transfer output to be activated. Once activated, it will
remain active even if the frequency dips below 50
Hz.
Upon restoration of utility source voltage above a
preset level, generator circuit board action signals the
transfer switch to transfer loads back to that power
supply. After retransfer, the engine is signalled to shut
down.
The actual sequence of operation is controlled by
sensors and timers on a control logic circuit board,
as follows:
A. Utility Voltage Dropout Sensor
This sensor monitors utility source voltage.
If utility source voltage drops below about 65
percent of the nominal supply voltage, the sensor
energizes a 10 second timer.
Once the timer has expired, the engine will crank
and start if utility is still low.
B. Engine Warm-up Time Delay
This mechanism lets the engine warm up for
about five (5) seconds before the load is transferred to the standby source.
15
Section 3 Operation
Air-cooled Generators
C. Standby Voltage Sensor
This sensor monitors generator AC output voltage. When the voltage has reached 50 percent of
the nominal rated voltage, transfer to standby
can occur.
D. Utility Voltage Pickup Sensor
This sensor monitors utility power supply voltage. When that voltage is restored above 75 percent of the nominal source voltage, a retransfer
time delay starts timing.
E. Retransfer Time Delay
This timer runs for about 15 seconds.
At end of a 15-second delay, circuit board action
de-energizes transfer relay in the transfer switch
if utility is still present.
Retransfer to utility power source then occurs.
F. Engine Cool-down Timer
When the load is transferred back to utility power
source, the engine cool-down timer starts timing.
The timer will run for about one minute, and the
generator will then shut down.

3. Once the red LED's stop flashing, the generator
will start and run for approximately 12 minutes
and then shut down. The exerciser is now set to
run at this time of day each week.
Example: If the "Set Exercise Time" switch is
pressed on Saturday afternoon at 2:00 p.m., the
generator will start and exercise for approximately 12 minutes every Saturday at 2:00 p.m..
NOTE:
If utility is still lost after 10 seconds, run the
engine up to 3600 RPM and transfer the load.
At this time the controller will exit the exercise
routine and assume full automatic operation.

PROTECTION SYSTEMS
3.6.1 LOW OIL PRESSURE SWITCH
This switch (Figure 3.3) has normally closed contacts that are held open by engine oil pressure during cranking and operating. Should oil pressure
drop below the 8 psi range, switch contacts close,
and the engine shuts down. The unit should not be
restarted until oil is added. The AUTO/OFF/MANUAL
switch must then be turned to OFF and then back to
AUTO.
3.6.2 HIGH TEMPERATURE SWITCH
This switchs contacts (Figure 3.3) close if the temperature should exceed approximately 144 C (293
F), initiating an engine shutdown. The generator will
automatically restart and the LED on the generator
control panel will reset once the temperature has
returned to a safe operating level.
Figure 3.3 Low Oil Pressure and
High Temperature Switches
Low Oil Switch
High Temp Switch
The exerciser will only work in the AUTO mode
and will not work unless this procedure is performed. The exerciser will need to be reset every
time the 12-volt battery is disconnected and then
reconnected, and when the 15A fuse is removed.
The 16 and 18kW units have a low speed exercise
option. Dip switch 1 on the control board is factory
set to OFF. This allows the engine to run at a slower
speed during weekly exercise periods for quieter
operation. If this Dip switch is set to ON, the generator will exercise at it's normal speed.
This DIP switch position is only read at board power
up. If the DIP switch position is changed, power to
the board must be cycled for the micro controller to
recognize the new DIP switch position.
Low speed exercise will be handled as follows:
1. The standard start sequence will be initiated.
2. The unit will run at 2,400 RPM.
3. If utility is lost during exercise, the controller will
do the following:
Wait 10 seconds for utility to return.
If utility returns within 10 seconds, continue to
exercise at 2,400 RPM.

3.6.3 OVERCRANK
This feature prevents the generator from damaging
itself when it continually attempts to start and another problem, such as no fuel supply, prevents it from
starting. The unit will crank and rest for a preset
time limit. Then, it will stop cranking, and the LED
on the generator control panel will light indicating an
overcrank failure. The AUTO/OFF/MANUAL switch
will need to be set to OFF and then back to AUTO to
reset the generator control board.

3.6.4 OVERSPEED
This feature protects the generator from damage by
shutting it down if it happens to run faster than the
preset limit. This protection also prevents the generator from supplying an output that could potentially
damage appliances connected to the generator circuit. Contact the nearest Authorized Dealer if this
failure occurs.
3.6.5 RPM SENSOR FAILURE
10, 13, 16 & 18kW Operation
During cranking, if the board does not see a valid
RPM signal within three (3) seconds, it will shut
down and latch out on RPM sensor loss.
During running, if the RPM signal is lost for one full
second the board will shut down the engine, wait 15
seconds, than re-crank the engine.
18
If an RPM signal is not detected within the first
three (3) seconds of cranking, the control board
will shut the engine down and latch out on RPM
sensor loss.
If the RPM signal is detected, the engine will start
and run normally. If the RPM signal is subsequently lost again, the control board will try one more
re-crank attempt before latching out and flashing
the over speed LED.
7 KW Operation
During cranking, if the control board does not see a
valid RPM signal within three (3) seconds, it will shut
down and latch out on RPM sensor loss.
The control board will continue the standard crank/
reset sequence. At the end of the crank/reset cycle,
the control board will latch out on over crank (if RPM
are never seen). The control board will not energize
fuel solenoid until it sees RPM.
In the event the control board sees RPM during
crank, and then RPM are lost during crank, the control board will shut down the engine (turn off fuel and
ground magneto). The control board will wait two
(2) seconds and then continue the crank sequence
with the next crank cycle (if additional crank cycles
exist).
3.6.6 LOW BATTERY
The microprocessor will continually monitor the
battery voltage and turn on the Low Battery LED if
the battery voltage falls below 11.0 volts for one (1)
minute. No other action is taken on a low battery
condition. Low battery voltage is a non-latching alarm
which will automatically clear if the battery voltage
rises above 11.0 volts. Battery voltage is NOT monitored during the crank cycle.
4.1
FUSES
The 15-amp fuse on the generator panel protects the
DC control circuit against overload (Figure 4.1). This
fuse is wired in series with the battery output lead
to the panel. If this fuse element has melted open,
the engine will not be able to crank or start. Replace
this fuse using only an identical 15-amp replacement
fuse. To replace the fuse, push the fuse holder cap
down and rotate it counterclockwise. Whenever the
fuse is removed or replaced, the exercise timer needs
to be reset.

ADJUSTING GH-410/GT-530/990
VALVE CLEARANCE
After the first six (6) months of operation, check
the valve clearance in the engine, adjust if necessary.
Important: If feeling uncomfortable about doing
this procedure or the proper tools are not available,
please contact the Authorized Dealer for service
assistance. This is a very important step to insure
longest life for the engine.
To check valve clearance:
The engine should be cool before checking. If
valve clearance is 0.002" - 0.004" (0.05 - 0.1mm),
adjustment is not needed.
Remove spark plug wires and position wires away
from plugs.
Remove spark plugs.
Make sure the piston is at Top Dead Center (TDC)
of its compression stroke (both valves closed). To
get the piston at TDC, remove the intake screen at
the front of the engine to gain access to the flywheel
nut. Use a large socket and socket wrench to rotate
the nut and hence the engine in a clockwise direction. While watching the piston through the spark
plug hole. The piston should move up and down.
The piston is at TDC when it is at its highest point
of travel (Figure 4.10).
To adjust valve clearance (if necessary):
Make sure the engine is at 60 to 80 F.
Make sure that the spark plug wire is removed
from the spark plug and out of the way.
Remove the four screws attaching the valve cover.
Loosen the rocker jam nut. Use an 10mm allen
wrench to turn the pivot ball stud while checking
clearance between the rocker arm and the valve
stem with a feeler gauge. Correct clearance is
0.002-0.004 inch (0.05-0.1 mm).
NOTE:
Hold the rocker arm jam nut in place as the pivot
ball stud is turned.
When valve clearance is correct, hold the pivot ball
stud in place with the allen wrench and tighten the
rocker arm jam nut. Tighten the jam nut to 174
in/lbs. torque. After tightening the jam nut, recheck
valve clearance to make sure it did not change.
Install new valve cover gasket.
Re-attach the valve cover.
NOTE:
Start all four screws before tightening or it will not
be possible to get all the screws in place. Make
sure the valve cover gasket is in place.
Install spark plugs.

ATTENTION AFTER SUBMERSION
If the generator has been submerged in water, it must
not be started and operated. Following any submersion in water, have an Authorized Dealer thoroughly
clean, dry and inspect the generator. If the structure
(ex. home) has been flooded, it should be inspected
by a certified electrician to ensure there won't be any
electrical problems during generator operation or
when utility is returned.
4.8
4.10 CORROSION PROTECTION
COOLING SYSTEM
Air inlet and outlet openings in the generator compartment must be open and unobstructed for continued proper operation. This includes such obstructions as high grass, weeds, brush, leaves and snow.
Without sufficient cooling and ventilating air flow, the
engine/generator quickly overheats, which causes it
to quickly shut down. (See Figure 4.11 for vent locations.)
Make sure the doors and roof are in place during operation as running the generator with them
removed can effect cooling air movement.

de carga elctrica que normalmente funcionan
con una fuente de energa suministrada por la empresa de servicios elctricos, segn el cdigo, se requiere
instalar un interruptor de transferencia. El interruptor
de transferencia debe aislar eficazmente el sistema
elctrico del sistema de distribucin de la empresa de
servicios elctricos cuando el generador est en funcionamiento (NEC 700, 701 y 702). No aislar el sistema
elctrico por estos medios provocar un dao en el
generador y tambin puede provocar lesiones o la
muerte de los trabajadores de la empresa de servicios
elctricos debido a una retroalimentacin de energa
elctrica.
Si se detecta alguna prdida o dao al momento de la
entrega, solicite a las personas que realizan la entrega que
tomen nota de todos los daos en la factura de transporte
o que firmen debajo de la nota del consignatario donde se
informa acerca de la prdida o el dao.
Si se detecta una prdida o un dao despus de la entrega,
separe los materiales daados y contacte al transportista
para los procedimientos de reclamo.
Se entiende como "dao oculto" al dao del contenido de
un paquete que no est en evidencia al momento de la
entrega pero se descubre despus.
1.2
SISTEMAS DE PROTECCIN
A diferencia del motor de un automvil, es posible que el
generador tenga que funcionar durante perodos prolongados de tiempo sin que est presente un operador para
controlar las condiciones del motor. Por tal razn, el motor
est equipado con los siguientes sistemas para protegerlo
de las posibles condiciones que pueden producir daos:
1. Sensor de baja presin de aceite 4. Exceso de velocidad
2. Sensor de alta temperatura
5. Sensor de RPM
3. Falla de arranque
6. Batera baja
Existen lecturas LED en el panel de control para informarle al personal que se produjo una de estas fallas. Tambin
hay una luz LED de la configuracin del sistema que se
ilumina cuando todas las condiciones descritas en la seccin "Luz LED de la configuracin del sistema" son reales.
(Consulte la seccin "Sistemas de proteccin" para obtener
ms detalles).

REQUISITOS DEL NEC PARA EL
DISYUNTOR DE INTERRUPCIN DEL
CIRCUITO POR FALLA DEL ARCO
ELCTRICO PARA DORMITORIOS
En el ao 2001, el Cdigo Nacional de Electricidad (NEC)
introdujo un requisito para las construcciones nuevas. Este
nuevo requisito indica que se deben utilizar Interruptores
de circuitos por falla del arco elctrico para proteger el circuito derivado completo que alimenta el dormitorio de una
vivienda. A continuacin, se indican los requisitos vigentes
del NEC.
1.3.1 SECCIN 210.12 SOBRE LA
PROTECCIN DEL INTERRUPTOR
DEL CIRCUITO POR FALLA DEL ARCO
ELCTRICO
1. Definicin: un interruptor de circuito por falla del arco
elctrico es un dispositivo diseado para brindar proteccin contra los efectos de las fallas del arco elctrico
al reconocer caractersticas nicas del arco elctrico y
funcionar para desactivar el circuito cuando se detecta
una falla en el arco elctrico.
2. Dormitorios de unidades habitacionales: todos los circuitos derivados que alimentan tomacorrientes de 125
voltios, monofsicos, de 15 y 20 amperios, instalados
en dormitorios de unidades habitacionales deben estar
protegidos por un interruptor de circuito por falla del
arco elctrico listado para brindarle proteccin a todo
el circuito derivado.
La Seccin 210.12 requiere que se proporcione esa proteccin mediante el Interruptor de circuito por falla del arco
elctrico (Arc Fault Circuit Interruptor, AFCI) en los circuitos derivados que alimentan tomacorrientes (receptculos,
iluminacin, etc.) en dormitorios de viviendas. El requisito
se limita a los circuitos de 15 y 20 amperios y 125 voltios.
No existe prohibicin alguna contra la provisin de proteccin AFCI en otros circuitos ni en otras ubicaciones que no
sean dormitorios. (Contina en la pgina 7.)
