[QUOTE="Phoenix, post: 504670, member: 8133"] If, of course you can measure R1R2 safely, which if you cant isolate the board outside of set hours, you are back to working in a live board, think there was one member here who had a bit of a flash measuring R1R2 on an EICR, think one of the team was at the isolator for a water heater, while another switched off the MCB and held a link between earth and the output of the MCB, unfortunatly the cirucit had been muddle with the ring, the other end of which (along with the water heater circuit) being fed by another MCB. Like I said, not a problem on a new installation where you do the R1R2 tests before the board goes live, but on an existing installation where downtime has to be limited, and then you do need the power on for IDing cirucits its a bit of none starter [/QUOTE]
