Test & Inspection
The electrical tests must be completed in a strict order and dead tests must be completed satisfactorily before the live test commence.
The dead tests are:
Continuity of protective conductors including main and supplementary bonding
Continuity of ring final circuit conductors
Protection by separation of circuits
Earth electrode resistance
Electrical Testing: Live tests
The live electrical tests follow on from the dead test. With suitable results the periodic inspector knows that it is safe for him to continue working on a live installation.
Live tests are classified as follows:
Protection by automatic disconnection of supply
Earth fault loop impedance
Operation of residual current devices
Prospective fault current
