Frequently us taggers get bitched at by construction folk because we follow the Construction and Demolition Electrical Standard when testing and tagging their gear, here is your chance to tell the standards committee what you think the standard should say
The changes the committee have tabled can be seen here, the NZ committee are seeking feedback on builders temporary supplies, but their link isn't working at the moment.
My first amendment to the proposed changes:
L.3 Connection requirements
The construction power supply switchboard shall be provided within the site boundary and in accordance with 2.3, and additionally, shall provide all of the following:
"NOTE The requirement of the switchboard within the site boundary is to prevent extension cords to the building site from crossing road reserve.
(a) The system of supply shall be TN-C-S (MEN) single phase;
(b) The provision of a 16 A socket outlet complying with IEC 60309 for the connection and supply of a transportable structure (connectable installation in NZ) is optional"
The first change, provision of a 16A socket outlet "shall be provided" There should be nothing optional about provision of suitable supplies to run concrete polishers, welders, dust extraction systems on any site (along with a suitable supply outlet for a connectable installation such as a site hut, workers smoko room etc on any building site
