Standards New Zealand is seeking feedback on the draft Amendment No. 2 to NZS 6114:2006 Electrical installations – Requirements for the safe supply of electricity to installations/facilities and equipment operating at non-standard voltages and frequencies. Amendment No. 2 is now available for public comment.

Amendment No. 2 adds Section 6: Aviation electrical installations and equipment. It also adds two related appendices.

  • Section 6 covers aviation electrical installations that supply power at voltages or frequencies other than SLV to aircraft, airport aprons, aviation equipment, and aviation repair workshops.
  • It 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.

Section 6 of NZS 6114:2006 was formally withdrawn in January 2007, six months after the standard was published. This left the civilian and military aviation industries in New Zealand without a standard for engineers and electricians who design or repair aircraft electrical reticulation systems in the airport environment. This amendment reinstates the section and updates it.

The draft Amendment No. 2 is available for public comment for 8 weeks. All comments submitted during this period are reviewed by the technical committee before the adoption ballot is held and the amendment published.

You can view or download and submit your comments to the draft Amendment No. 2 on the Standards New Zealand website.
