Right, not much seems to be happening tonight so I'm going to ask you some questions. Now I'm interested in this testing you talk of, and from what i've picked up seems to involve Earth Loop Impedance, Insulation test, and testing of the MCB.
In terms of Earth Loop Testing - is it really just ensuring that each part of the circuit is continuous with the earth? (a sort of continuity test so to speak)?
Surly something is ether connected to earth or not and so how can we put numbers to it? Ze
When testing an installation, say with a CU change, WHERE do you measure it? Each fitting? Each circuit? Once?
Bonding is earth to incoming gas and water (unless in plastic) - is this tested too?
What about supplimentary bonding? Do we make sure the bath taps are earthed?
I can imagine it's different depending on the earth arrangement (rod = TT, from electricity company = PME)
(I'll ask about the other 2 parts another night)
