AS/NZS 3012:2011 Electrical installations- Construction and demolition sites, is an important Standard for electricians to use when working on large construction sites. It provides useful guideline as to the requirements for electrical systems such as temp power, portable outlet devices and temporary lighting often used in these locations.
Often the building contractors you are working for are unaware of the sites safety requirements for the electrical systems and as such pass the risk to you the electrical contractor.
On top of this is very useful booklet from Worksafe NZ (WKS- 5 Electrical Safety on Construction Sites) as per link below. Section 5 "CHECKING YOUR ELECTRICAL EQUIPMENT IS SAFE" is well worth reviewing.
Often the building contractors you are working for are unaware of the sites safety requirements for the electrical systems and as such pass the risk and compliance to you the electrical contractor.
As the requirements of jobsite Test and Tag are often totally mis-interpreted of poorly understood, section 5 sets out the requirements from Worksafe NZ's point of view. The focus is on the use of safe RCD's and visual inspections/checks prior to use by the person about to use portable electrical equipment.
For electrical contractors working on construction sites, a lot more effort needs to go into the regular testing of the site RCD's with proper RCD test instruments to ensure they comply with ER24 of the Electricity Safety Regulations. This applies to site RCD protected portable socket-outlet assemblies (PSOAs) and the RCD's fitted at builders temp locations.
