Design and test parameters for Portable Socket Outlet Assemblies

Workers on construction and demolition sites should be aware of the requirements of AS/NZS 3012:2003 Electrical installations - Construction and demolition sites when purchasing Portable Socket Outlet Assemblies (PSOAs) for use on their worksites.

Portable Socket Outlet Assemblies now have a new standard, AS/NZS 3190:2009 Approval and test specification - Residual current devices (current operated earth-leakage devices. Published in February this year, the standard is an update of AS/NZS 3190:2002 and now includes design and test parameters for PSOAs.

Among other requirements, the new standard requires PSOAs to have:

• a minimum IP33 rating
• a heavy duty sheathed supply cord
• an over current circuit breaker complying with AS/NZS 3111 or AS/NZS 60898.1
• a residual current device (safety switch) to isolate all live conductors in event of an earth fault, and
• a marking requirement to 'test before use, do not use if test fails'.

Note: Normal powerboards for household or similar general use that comply with AS/NZS 3105 Approval and test specification - Electrical portable outlet devices and have an addition of a safety switch, may not comply with the requirements of AS/NZS 3190 as a PSOA.

Workers now have further options in meeting their safety obligations on a worksite, by requesting confirmation the PSOA has been type tested or certified as complying with AS/NZS 3190 before they purchase the product.
