Topic: Earth Loop Impedance Tests

As an electrician why do we not specify Earth Loop Impedance tests per pole on a regular basis ?

Its the only true way to determine if the Earth Fault Loop is sufficiently low to ensure the Fault current protection will trip.

Topic: PSC spares

Does anyone have or know of a supply of spares for older PSC controllers? We are specifically after site ID cards and flasher units. Good condition second hand is fine. We still have several older controllers and are running short of a few spares...

Cheers,
Blair
