Electrical code of practice and safety regulations

A person who carries out any construction, building, excavation, or other work on or near an electric line must maintain safe distance.

Regulation 17 of the Electricity (Safety) Regulations 2010 requires that a person who carries out any construction, building, excavation, or other work on or near an electric line must maintain safe distances in accordance with New Zealand Electrical Code of Practice for Electrical Safe Distances (NZECP 34:2001).

Minimum safe distances have been set by NZECP 34 primarily to protect persons, property, vehicles and mobile plant from harm or damage from electrical hazards. 

Key requirements of NZECP 34 include: 

  • The distance between any live overhead electric line and any part of any mobile plant or load carried shall be “AT LEAST 4.0 METRES”, unless the operator has received written consent from the overhead electric line owner allowing a reduced distance. 
  • The distance between any exposed live parts and persons (including tools held) shall be “AT LEAST 4.0 METRES”, unless the person has received written consent from the owner of the live parts allowing a reduced distance. 
  • Mobile plant or any load carried shall not operate above the conductors of any overhead electric line unless the operator has received written consent from the overhead electric line owner to work above the overhead electric line.

Hot water load testing under way ahead of winter

Until mid‑April, we’re working closely with retailers to carry out hot water load testing as we prepare our network for the coming winter season.

These tests run for a couple of hours each day, Monday to Friday, with no testing taking place over weekends. Because each test window is relatively short, customers are unlikely to notice any changes to their hot water supply.

The purpose of this work is to help us better understand how much controllable load is available during the summer months. Gaining accurate insights now means we can model customer savings more effectively by reducing system load at peak times. It also helps us assess whether this load flexibility could assist Transpower in deferring an upcoming local transmission upgrade.

This testing is an important part of ensuring a resilient, efficient network that supports our community.
