While working on a building or construction project, you may need to organise a temporary power supply.
Here you can find out when a temporary power supply is used, how to get connected and some technical and safety advice.
A builder's temporary power supply is a connection on site to give an electricity supply for building or construction work.
It can be used for up to one year, with a short extension available if work is close to completion. After this time it needs to become a permanent connection, or disconnected.
It can't be used for providing residential, leisure or commercial power supply.
All builder's temporary supply are metered and can be either 1 phase (30/32A) for housing or small commercial construction, or 3 phase (60/63A) for large commercial or industrial construction.
An Installation Control Point (ICP) number is allocated to each builder's temporary supply, and this is transferred when the connection is changed to a permanent supply.
Here's some useful information when installing your builder's temporary supply:
All builder's temporary supply installations need to conform to relevant clauses in the Electricity (Safety) Regulations 2010 and any subsequent amendments; and Part 2 of AS/NZS 3000: Electrical Installations (known as the Australian/New Zealand Wiring Rules).
They also need to meet both Northpower network standards and Worksafe NZ safety requirements.
Once the installation is completed, a valid Certificate of Compliance (COC) needs to be submitted before we can liven the supply.
