Yes, I know getting to zero load on some circuits could be an issue. I want to make insulation resistance measurements using a megohmmeter on those circuits that I am confident in getting to zero load, which will be almost all of them. My question is, can I meg thru outlets and light switches or...
For making a spot IR test (good/not good) on circuits in a residence, wouldn't it be OK for the general purpose circuits to disconnect the lighting fixtures and leave the wall outlets (with no load) and closed light switches in place? If this combination did not test above about 1 megohm, then...
