Installations and networks

High voltage electrical installations

Most high voltage installations are unique to their application and are designed according to electrical engineering safety principles. As a result, the Regulations that apply set fundamental safety requirements only.

Low and extra low voltage electrical installations

Electrical installations at low and extra low voltages need to be designed and installed in a way that ensures they will be safe to use. There are processes surrounding design, construction, certification, inspection, connection and periodic verification to make sure safety is maintained throughout the life of the installation.

Who must comply

Everyone who designs or does work on installations, supply networks, fittings and appliances in New Zealand must ensure they comply with New Zealand’s established regulatory framework. This also applies to everyone who supervises the design or work.

Works

‘Works’ means any fittings that are used, or designed or intended for use, in or in connection with the generation, conversion, transformation, or conveyance of electricity; but does not include any part of an electrical installation.
