Electrical installations – Connectable electrical installations and supply arrangements Part 2: Connectable electrical installations
|Publication Date:||18 November 2022|
This Standard sets out the requirements for connectable electrical installations used for the purposes of accommodation, habitation or other residential, commercial or recreational uses that are intended for connection to external low voltage a.c. (see Clause 1.4.28) supply systems by either -
(a) a detachable supply lead; or
(b) a supply lead directly connected to the connectable electrical installation.
A connectable electrical installation (see Clause 1.4.8) may comprise a number of types of low voltage supplies, however where a connectable electrical installation has the facility to connect to an external supply (see Clause 188.8.131.52), it is required to comply with this Standard.
This Standard also sets out requirements and provides guidance for the installation of extra-low voltage (see Clause 1.4.28) systems installed within connectable electrical installations that are intended for detachable connection to external low voltage a.c. supply systems.
For the purposes of this Standard, the term "connectable electrical installation" includes vehicles and units with or without wheels that can readily be moved from one site to another, either under their own motive power or by some other means.
The particular requirements of this Standard replace, modify or are additional to the general requirements of AS/NZS 3000 for the electrical wiring of connectable electrical installations.
These requirements are intended to protect persons, livestock, and property from electric shock, fire and physical injury hazards that may arise from a connectable electrical installation that is used with reasonable care and with due regard to the intended purpose of the electrical installation.
In addition, guidance is provided so that the electrical installation functions correctly for the purpose intended.
Relocatable units (see Clause 1.4.19) including, but not limited to:
(c) Site offices.
(e) Meeting offices.
(h) First aid rooms.
(i) Toilet facilities.
(j) Washroom facilities.
(k) Other facilities.
(l) Tents for accommodation.
(m) Rigid and non-rigid annexes.
Recreational vehicles (see Clause 1.4.18) including, but not limited to:
(b) Camper vans.
(c) Motor homes.
(d) Camper trailers.
(e) Pop top caravans.
(f) Tent trailers.
(g) Fifth wheel caravans.
(h) Slide on campers.
(i) Converted buses or trailers.
Non-recreational vehicles (see Clause 1.4.15) including, but not limited to:
(a) Horse floats.
(c) Livestock or car transporters.
(d) Vehicles such as food and drink vending vans and trailers.
(e) Educational display caravans and trailers, mobile classrooms.
(f) Television outside broadcast vans.
(g) Mobile stages.
(h) Display units e.g. mobile electronic score boards and advertising signs, mobile traffic information signs.
(i) Hybrid, any towable or self-propelled vehicle that does not fit specifically into any of the above categories.
(j) Other vehicles such as emergency vehicles that have an external low voltage connection.
(k) In New Zealand, mobile medical connectable installations complying with the requirements of this Standard.
NOTE Further requirements for mobile medical connectable installations can be found in NZS 6115.
This Standard does not apply to connectable electrical installations that are immobilized or fixed in position and directly connected by installation wiring, and where the ability for relocation is not intended to be maintained. These structures are subject to the requirements of AS/NZS 3000.
Examples include but are not limited to the following:
(a) Vehicles, recreational vehicles and non-recreational vehicles that are rendered immobile, e.g. tramcars, buses, etc.
(b) Relocatable units, e.g. homes, huts, construction sheds and tents.
In addition, this Standard does not apply to the following:
(i) Vehicles forming part of an amusement ride or device. These vehicles may be subject to the requirements of AS 3533.
(ii) Structures for the provision of entertainment that do not contain an electrical installation e.g. circus and carnival tents and temporary vending stalls. These structures are subject to the requirements of AS/NZS 3002.
(iv) Other vehicles such as emergency vehicles that do not have an external low voltage connection. In the case of these vehicles, this Standard may be used as a guide.
(v) Non-recreational vehicle fitted with a permanently attached supply lead or inlet plug for the connection of a single item of electrical equipment, such as the following:
(A) Trailed concrete mixer.
(B) Single on board battery charger, only.
(C) Mobile elevated work platform (MEWP) battery charger only.
(D) Mobile battery powered equipment charger.
(E) Message boards and portable traffic advisory systems.
This Standard does not cover requirements for the following:
(1) Re-generative drive/braking systems.
(2) Battery charging while moving.
(3) Enhanced protection arrangements that may be subject to design and original equipment manufacturer's requirements.
This Standard does not apply to automotive wiring systems, electrical fittings, and electrical wiring whose primary function relates to propulsion or roadworthiness of a vehicle.
