Going back to a job on Thurs.
Changed the CU & the RCD trips when the socket CB is turned on. I've got my trusty fault finding list ready, but just to confirm if there was a borrowed neutral from a lighting circuit to sockets or vice versa then wouldnt the RCD trip only when one of the lights were switched on or something was plugged in? I'm 99% sure everything was unplugged & all lights off when I did the CU change
