18 - ANNEX - SUMMARY OF TECHNICAL DEVIATIONS BETWEEN THIS STANDARD AND IEC 621-3

Specifies general requirements for the equipment and ancillaries associated with the electrical installation. Sections deal with electrical components, rotating machines, transformers, static converters, switching devices, cable selection and application, cable connectors, cable drums, control circuits and control devices, safety circuits and safety devices, and fire detection and protection systems. Technically equivalent to IEC 621-3.

This standard sets out requirements for the equipment and ancillaries associated with electrical installations within the scope of AS 3007.1.
