PREFACE
This Standard was prepared by the Joint Standards Australia/Standards New Zealand
Committee EL-001, Wiring Rules, to supersede AS/NZS 3001:2001.
This Standard incorporates Amendment No. 1 (May 2012). The changes required by the
Amendment are indicated in the text by a marginal bar and amendment number against the
clause, note, table, figure or part thereof affected.
This edition was prepared to update the requirements for electrical installations associated
with transportable structures and vehicles (formerly known as relocatable premises) and
their site supplies following the issue of AS/NZS 3000:2007. It includes provisions for the
connection of electric power to various types of transportable structures and vehicles,
including caravans and various temporary structures such as tents used for domestic and
commercial purposes.
This Standard differs from AS/NZS 3001:2001 in several respects including the following:
(a) The text 'relocatable premises' has been changed to 'transportable structures and
vehicles' and this edition covers a larger range of installations.
(b) The underground wiring requirements for caravan parks have been updated.
'c
2 (c) Diagrams showing the recommended method of connecting a transportable structure
to a generator set/inverter have been added.
C

(d) Appendix C covering verification requirements for connectable installations in New

Zealand has been added.
C
(0 The application of this Standard may be required by legislation from a date to be set by the
::,
Cl
relevant regulating authority. If work on an installation was commenced before publication
C
of this edition, the relevant regulatory authority or electricity distributor may grant
C
permission for the installation to be completed under AS/NZS 3001:2001 as applicable.
�
rl The following background regarding differences between requirements in Australia and
1: New Zealand is provided as general information for the reader.
E
rl In New Zealand, many caravans are fitted with a neutral-earth connection. This precludes
providing RCD protection to the caravan by the installation of RCDs on the supply side of
.,..'°
0 the neutral-earth connection. In Australia, such a connection is traditionally not fitted.
N

1u'
::E
As this Standard applies to new site installations and new transportable structures and
(0
0
vehicle installations, the decision has been made that there will be no neutral-earth
C
0 connection within the transportable structures and vehicles and all site supplies will have
<i::
::J RCD protection.
t-
(/)
In many parks there will be a mixture of new service pillars with RCD protection and old
:::i
<i::
service pillars without. In New Zealand, the location of transportable structures and
� vehicles with a neutral-earth connection becomes a site management issue.
� In the case of caravan parks which only have pillars with RCD protection, transportable
UJ
>
z:::i structures and vehicles with a neutral earth connection will not be permitted to connect to a
z power outlet.
0
In New Zealand, it is typical for the plug on the supply lead to transportable structures and
w vehicles and hence for all socket-outlets intended to provide electrical power to such
0
UJ
LL
transportable structures and vehicles to comply with IEC 60309. In Australia, 15A, 3 pin,
>
.0 flat-pin plugs complying with AS/NZS 3112 are the norm. This Standard reflects changes in
"'"'
"O
Cl) New Zealand allowing the provision of socket-outlets complying with AS/NZS 3112 to be
Cl)
u installed in New Zealand caravan parks.
u
<i::
3 AS/NZS 3001:2008

In Australia, the use of round-pin plugs and socket-outlets complying with AS/NZS 3123 is
allowed but flat-pin type connections are the type most commonly used for single-phase
supply to transportable structures and vehicles.
Al In Australia it is required that all circuit-breakers and switches in the wiring of
transportable structures and vehicles connected by means of a detachable connection
operate in all live (active and neutral) conductors. This is not required in New Zealand.
Appendices A and B are included to provide additional supportive or background
information and advice. These appendices do not form an integral part of this Standard and
are identified as 'informative'.
The word 'shall' introduces a requirement that is to be followed strictly in order to comply
with the Standard. The word 'should' introduces a suggestion or recommendation only.
Al A New Zealand-only amendment was issued in May 2009 to cover the removal of the
neutral to earth link in New Zealand caravans built before 1993. This was necessary to
allow the introduction of RCD protection to service pillars in caravan parks that was
brought about by the issue of AS/NZS 3001 :2008. This removal of the link was also
required for caravans located adjacent to and supplied from a domestic residence that had
socket outlets protected by RCDs in accordance with AS/NZS 3000. The New Zealand
amendment was incorporated into the Standard by Amendment No. 1 (2012).

'o
A new requirement introduced by Amendment No. 1 (2012) as Clause 3.10.3 highlights the
2
C
additional inspection required for the periodic testing required for a re-issue of a
·;::
Q.

New Zealand Warrant of Electrical Fitness. A further requirement in Appendix C clarifies

2.2.6 Caravan park service pillars

2.2.6.1 Introduction
Typically, a caravan park service pillar will be part of a free standing structure situated
amongst a number of sites.
Typically, service pillars incorporate a switchboard for the mounting of overload, earth
leakage and control devices for the socket-outlets installed in the pillar.
Service pillars may contain other equipment subject to the requirements of AS/NZS 3000
and service pillars may also contain other services.
2.2.6.2 Location
Each caravan park service pillar shall be located so as to enable supply leads of the
minimum length as specified in Clause 5 .1.3 to be connected to each applicable site in
accordance with Clause 5.2.
2.2.6.3 Accessibility
Caravan park service pillars shall be readily accessible, as detailed in AS/NZS 3000.
2.2. 7 Socket-outlets

2.2. 7.5 Protection against earth leakage current

Socket-outlets used to supply transportable structures shall be provided with protection
against earth leakage current as follows:
(a) Each socket-outlet shall be protected by a residual current device (RCD) with a rated
operating current not exceeding 30 mA, that operates in all live (active and neutral)
conductors.
(b) In New Zealand, the RCD shall be a Type A RCD.
NOTE: This does not preclude protection of more than one socket-outlet by a single RCD;
however, it is recommended that one RCD be provided for each socket-outlet to reduce both the
likelihood and consequences of unwanted tripping.
2.2.7.6 Control
Each socket-outlet used to supply transportable structures shall be controlled by its own
individual control switch that shall be-
(a) mounted immediately adjacent to the socket-outlet it controls or is otherwise suitably
identified as to the socket-outlet it controls; and
(b) clearly identified to indicate the off and on positions.
