[QUOTE="ProDave, post: 327639, member: 6969"] Very true. Perhaps a new test we should all do (if you don't already), is turn off all MCB's and measure to ensure the circuits really have turned off. I thought you were going to post something along the lines of a pre wired split load board had been assembled wrong, so the L feed to the RCD side came from the INPUT to the main switch. So with the main switch off, all the RCD side still had L connected, but not N. I found one like that once. [/QUOTE]
