thanks for replys guys. its called benchmark certification.my question regarding isolation was prob not clear. i meant do you have to use a proving unit ?? can i not voltage test with supply on . and then turn main switch off check for voltage on load side n then prove its dead by retesting...
hi all, looking at all part p schemes at moment, and im leaning towards the benchmark(think its corgi) scheme as its cheap and i dont think not having napit etc names on my van will affect me much. just wondered if anybody has used them n was it a good scheme ?
cheers
pete.
