This document applies to electrical design, installation, and testing in general which is developed to comply with the requirements of AS/NZS 3000, Wiring rules.In addition, there are State and Territorial legislature requirements that must be applied in the design of electrical installations. These requirements are generally incorporated in the Electricity Distributor Service and Installation Rules, and will be referred to in this document as the “Service Rules”.While the requirements and terminology of the Electricity Distributor Service and Installation Rules have been acknowledged, it is not intended that this document address every possible combination of these rules, and it is to that extent intended to be generic.The designer using this document is to check the requirements of the Electricity Distributor Service and Installation Rules, and is to check with the Electricity Distributor for any special requirements. The designs may be modified as necessary.This Handbook is not a replacement for AS/NZS 3000, and the user must refer to AS/NZS 3000 for guidance on the application of the Standard in all cases.The technical information contained in the complying solutions is not a replacement for the AS/NZS 3008.1 series, and the user must refer to the appropriate part of that standard for guidance on the selection of cables for Australia and New Zealand.This handbook is not intended to address the detailed design and planning requirements for:a) High voltage electrical installation.b) Prospective short-circuit currents exceeding 20 kA. c) Hazardous locations (see the AS/NZS 2381 series).Where these electrical installations arise, an electrical designer experienced in the type of project envisaged should be used to undertake the planning and design.
