Just done a CU change, actually a CU move, so the room where the CU used to be can be turned into a bathroom
All went well. Job done in 2 halves as I was also moving a separate heating CU for the Big electric boiler.
So customers says "there's a problem with the landing light it sometimes trips the rcd"
So I take a look. First observation it turns on in one switch combination, but in the other combination it won't turn on at all. How odd. Undo the switch plate, which is the only new looking metal switch plate in sight, and there are only 2 wires connected to the landing light switch. But there are 3 wires connected to the hall light switch which is only switched from that one switch. Yes someone has swapped the switch and made a right mess and got it all jumbled up.
But it never did trip anything, it just did not work properly. Why did he not just say "can you have a look at the landing light it isn't switching properly"?
