Notes:
1. This form is to be used as a checklist for visual inspection acceptance only. Other acceptance criteria such as dielectric
properties test, insulation resistance test and functional test shall use the forms provided by the manufacturer. S.O Rep is
advised to begin the FAT with the visual inspection test ahead.
2. Prior departure to the factory, SO Representatives (SORs) are recommended to bring together:
 Documents : Approved Shop Drawing of Switchboard, BQ & Material List as per contract
 Tools : Digital Caliper, Measuring Tape, Torchlight, Digital Camera
3. Upon arrival and prior of any testing, SO Representatives are required to check/ensure:
a. Date of calibration status of the instruments to be used for testing. (Calibration validity: 2 years)
b. Certificate of the manufacturer’s competent person who will in charge for the testing. (Min. AO)
c. Brand & Model of the material installed had been approved during construction stage as referred to
material approval list (comply to J-MAL and material list as per contract).
d. Inspect thoroughly compliance of the manufactured switchboard with the approved shop drawing

B. TEST PROCEDURES (FOR LIGHTING CIRCUITS ONLY)


It should be noted that the continuity and insulation resistance tests for lighting circuit described below can only be
applied to a 'loop-in' wiring system only

1.0 CONTINUITY OF CPC IN LIGHTING CIRCUIT


1.1 Test method 1 (CPC conductor terminated at the last point of the circuit and using the neutral conductor
as a return lead)
1.1.1 Connect the neutral conductor to the CPC conductor (earth wire) at the last point of the circuit under test.
1.1.2 Test between neutral and earth of the circuit at the DB.
1.1.3 Record the test result obtained.
1.1.4 The readings should be compared with the "Resistance of copper conductors" table for a particular length
and size.

1.2 Test method 2 (CPC terminated at the switch panel and using the phase conductor as a return lead)
1.2.1 Connect the phase conductor (phase wire) to the CPC conductor (earth wire) at the switch panel.
1.2.2 Test between the phase and earth of the circuit at the DB.
1.2.3 Record the test result obtained.
1.2.4 The readings should be compared with the "Resistance of copper conductors" table for a particular length
and size.

2.0 INSULATION RESISTANCE IN LIGHTING CIRCUIT


2.1 A d.c voltage not less than twice (2x) the nominal voltage of the circuit concerned (r.m.s value for an a.c supply)
shall be applied for the measurement of insulation resistance, provided that the test voltage need not exceed 500
V d.c for installations rated up to 500V.

2.2 Test method (CPC conductor terminated at the last point of the circuit)
2.2.1 Test between the phase (join together all phase conductors at the switch panel) and the neutral at the DB.
2.2.2 Repeat the test for phase to CPC.
2.2.3 Test between the neutral and the CPC at the DB.
2.2.4 A value of less than 100MΩ on a final circuit is to be unacceptably low and require further investigation.

3.0 For Ring Final Circuits, Regulations 612.2.2 of BS7671:2008 calls for the continuity of EACH live conductor (phase
and neutral) and the protective conductor to be verified.

B. TEST PROCEDURES

1.0 CONTINUITY OF RING FINAL CIRCUIT CONDUCTORS


1.1 The phase, neutral and CPC conductors are identified and the end-to-end resistance of each conductor is
measured separately. Record the resistance readings. The readings should be compared with the "Resistance of
copper conductors" table for a particular length and size.
1.2 A finite reading confirms that there is continuity on the ring conductors under test.

2.0 CONFIRMATION OF RING FINAL CIRCUIT IS WIRED IN A RING (4 ends joined method)
2.1 Phase and neutral conductors cross-connected.
2.1.1 Connect the outgoing phase (P1) conductor to the returning neutral (N2) conductor. (P1 to N2)
2.1.2 Connect the returning phase (P2) conductor to the outgoing neutral (N1) conductor. (P2 to N1)
2.1.3 Measure the resistance across (P1 to N2) and (P2 to N1) and record the reading.
2.1.4 Measure the resistance at each socket on the ring between phase & neutral.
2.1.5 If the readings obtained from those Sockets wired into the ring are all the same and equal to the resistance
across (P1 to N2) and (P2 to N1) then the ring final circuit is confirmed.
2.1.6 If the readings are different, this will indicate the presence of a bridge or maybe due to incorrect
connections of the ends of the ring.
2.1.7 If they are connected P1 to N1 and P2 to N2 then the readings will increase or decrease as successive
measurements round the ring are taken.

2.2 Phase and CPC conductors cross-connected.


2.2.1 The above steps is then repeated but with the phase and CPC conductors cross-connected.

NOTES FOR ELECTRICAL INSTALLATION TEST
1. Before this test is undertaken, the earthing conductor to the earth electrode must be disconnected either at the electrode
or at the Main Earthing Terminal or Main Earthing Bar (MET/MEB) to ensure that all the test current passes through
the earth electrode alone. This will leave the installation unprotected against earth faults. SWITCH OFF SUPPLY
BEFORE DISCONNECTING THE EARTH.

NOTES:

1. Regulation 612.6 of BS7671 : 2008 calls for a polarity test to be carried out to establish that :
1.1 All fuses, circuit breakers and single pole switches are connected in the phase conductor only.
1.2 The centre contact of Edison Screw (ES) lampholders are connected to the phase conductor.
1.3 The polarity of socket outlets, other accessories and points of utilisation (eg luminaires) is correct.
2. The polarity of all circuits must be verified before connection to the supply.

3. Polarity testing must be carried with the supply isolated from the installation.

4. There are a number of ways in which polarity can be tested.


4.1 Visual checks where coloured cables are used.
4.2 Polarity test on lighting circuits, for example, can be conducted at the same time as that for continuity of CPC.
4.3 Indicators on RCCB testers and similar.

5. Of all of the above ways, the visual check is usually the easiest and this test is one that is best carried out by the person
installing and terminating cables, rather than by the 'test technicians.

(Notes & Test Procedure, TP)

A. NOTES

1. This Test Form is for RCCB, without time-delayed operation to IEC 61008.

2. This Test Form is to be used for testing a two (2) POLE-RCCBs and NOT applicable for four (4) POLE RCCBs.

3. Where is the circuit should the RCCB be tested?


The tests can be carried out immediately on the load side of the RCCB BUT it is preferred at the extremity of the
protected circuit (last point)

4. The RCCB should be tested with the load switch off or the load disconnected from the circuit.

B. TEST PROCEDURE (TP)

(i) RCCB Test Button


The RCCB should be operated first by the test button to check that the RCCB is not faulty before tests on the
installation are made.
The test button does not test the circuit, protective conductors or any earthing conductors or earth. The test button is
to ensure that the electrical and mechanical elements of the RCCB are functioning.

(ii) ½ I Test (Non-Trip Test):


A test at ½ (50%) of the rated tripping current of the RCCB for a period of two (2) seconds.
This acts as a 'no trip' test and the RCCB must not trip. This is intended to verify that the RCCB is not subject to
tripping when spurious 'nuisance' current appear in the circuit being protected.

(iii) I Test (Trip Test):


A Test at 100% of rated tripping current of the RCCB.
This act as a 'trip' test and the RCCB must break t he circuit within 300ms.
The choice of polarity, 0⁰ and 180⁰ enables the trip time to be measured accurately, as some RCCBs performs
differently if the current occurs at the beginning of a positive (0⁰) or a negative (180⁰)cycle.

(iv) 5I Trip Test (Trip Test):


This test mainly for RCCBs rated at not more than 30mA (ie. 30mA & 10mA). The RCCB must break the circuit
within 40ms at a residual current of 5IΔn. The choice of polarity, 0⁰ and 180⁰ enables the trip to be measured
accurately, as some RCCBs performs differently if the current occurs at the beginning of a positive (0⁰) or a
negative (180⁰) cycle.

(v) RCCB Test Button


Having completed the test, the effectiveness of the test button on the RCCB should again be checked to ensure that
everything is satisfactory.

(vi) RCCB Ramp Test


This test is to measure the trip current of an RCCB. Current level is slowly increase from half the rated tripping
current (0.5 x IΔn) of the RCCB. When the RCCB trips, the actual trip current (in milliamps) displayed. Very
useful diagnosing nuisance tripping of RCCB. RCCBs complying with IEC 61008 may operate within the range of
0.5 to 1.0 x rated tripping current of the RCCB. If the RCCB trips less than 0.5 x rated tripping current, replace the
RCCB.
