涵盖从新西兰境外采购的装置和设备，其工作电压和/或频率与新西兰境内使用的电压和/或频率不同，以确保其能够安全地由新西兰电力供应。飞机供电不在本标准范围内，也不包括危险区域、电气医疗或弱电装置或设备。注:修正案2于2019年2月7日发布，涉及第6节航空电气装置、设施和设备。本节适用于以SLV以外的电压或频率向飞机、机场停机坪、航空设备、航空支持和航空维修车间供电或用电的航空电气装置、设施和设备。 本节讨论了TN-C-S（MEN）配置和TN-C（地球返回）飞机配置之间的具体差异，并在两种不同的电力状态之间建立了安全合规桥梁。

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.
