Earth Fault Loop Compliance - AS/NZS 3019:2007

Extract from AS/NZS 3019:2007


2.5 Adequacy of overcurrent protective devices

(Extract) When verifying the adequacy of overcurrent protective devices, the interrupting capacity shall be verified by measurement of the fault loop impedance (and hence the fault level). 


4.2 General

(c) Conductors of cables are correctly identified and are connected to the correct terminals of fittings.


4.3 Switchboards

(a) The current rating and breaking capacity of protective devices are appropriate for the circuits they protect.


4.7.1 Earth continuity tests

(c) The resistance of protective earthing conductors does not exceed the maximum permitted.
