SNZ - AS/NZS 3760
In-service safety inspection and testing of electrical equipment and RCDs
|Publication Date:||24 June 2022|
This standard specifies procedures for the safety inspection and testing of low voltage single phase and polyphase electrical equipment, connected to an electrical supply by a flexible cord or connecting device, and that:
− Is new equipment placed into service for the first time;
− Is already in-service;
− Has been serviced or repaired;
− Is returning to service from a second-hand sale; or
− Is available for hire.
This standard also specifies procedures for the safety inspection and testing of:
− In Australia, residual current devices (RCDs) installed in the electrical installation;
− Portable inverters that generate or produce low voltage.
Typical examples of equipment covered by this standard are:
− Portable equipment, hand-held equipment and stationary equipment, designed for connection to the low voltage supply by a supply cord, an appliance inlet or pins for insertion into a socket-outlet;
− Cord sets, cord extension sets and portable outlet devices;
− Portable residual current devices (PRCD), outgoing assemblies for construction sites (ACS); portable socket-outlet assemblies (PSOA), outlet boxes;
− Flexible cords connected to fixed equipment in hostile environments;
− Portable power supplies (includes power adaptor/plug-pack, both of the safety isolating transformer and switch-mode type);
− Battery chargers, including those for commercial or industrial use;
− Portable and transportable heavy duty tools such as high-pressure washers and concrete grinders.
This standard applies only to equipment in-service at a place of work, public place, accommodation place, or equipment offered for hire.
This standard does not apply to
a) Electrical equipment installed at a height of 2.5 m or greater above the ground, floor or platform, where there is not a reasonable chance of a person touching the equipment and, at the same time, coming into contact with earth or any conducting medium that may be in electrical contact with earth or through which a circuit may be completed to earth;
b) Equipment that would need to be dismantled to perform the inspection and tests specified in this standard;
NOTE - If, for some reason outside the scope of this standard, equipment has to be dismantled to verify safety, this action is only to be performed by a technically qualified person.
c) Requirements for functional checks;
d) RCDs used in the supply to medical equipment within the scope of AS/NZS 3003 or NZS 6115;
e) Fixed equipment (except, in Australia, RCDs) or stationary equipment connected to wiring that forms part of the electrical installation and hence falls within the scope of AS/NZS 3000;
f) Medical electrical equipment, nor any equipment connected to medical electrical equipment in a medical electrical system, as defined in AS/NZS 3551;
NOTE - Test and inspection requirements for this equipment are contained in AS/NZS 3551.
g) Portable generators, within the scope of AS/NZS 3010;
h) In New Zealand, demonstration stock in retail or wholesale outlets;
i) In Australia, demonstration stock in retail or wholesale outlets, however the responsible person should regularly conduct a visual inspection.
