NZS 6114:2006

Electrical installations - Requirements for the safe supply of electricity to installations, facilities and equipment operating at non-standard voltages and frequencies

Covers installations and equipment sourced from outside New Zealand, and which operate at voltages and/or frequencies other than those used in New Zealand, ensuring they can be safely supplied from the New Zealand electricity supply. Supply of electricity to aircraft is outside the scope of this Standard, nor is it intended to cover hazardous area, electromedical or ELV installations or equipment. Note: Amendment 2 was published on 7 February 2019 and addresses Section 6 – Aviation electrical installations, facilities and equipment. This section applies to aviation electrical installations, facilities and equipment that supply or use electricity at voltages or frequencies other than SLV to aircraft, airport aprons, aviation equipment, aviation support, and aviation repair workshops. The section addresses the specific differences between the TN-C-S (MEN) configuration and the TN-C (Earth return) aircraft configuration and builds a safety compliance bridge between two disparate electricity regimes.
