AS/NZS 3017:2007
Electrical installations - Verification guidelines
Provides verification (inspection and testing) guidelines to ensure that electrical installations comply with the requirements of AS/NZS 3000 with regard to the prevention of people or livestock from sustaining an electric shock or injury from fire. Includes tests for earth continuity and resistance, insulation resistance, polarity, correct circuit connections, phase sequence, earth fault-loop impedance, operation of residual current devices (RCDs), measurement of the resistance of the earth electrode, measurement of touch voltage and continuity, and resistance of the incoming neutral.
