Afternoon all.
I've got a problem with an RCD tripping that I can't get my head round.
Upstairs lights are tripping the RCD. I switch off the MCB, but still tripping. So you'd think it was an earth/neutral fault. Nope. I remove the earth and the neutral from the board, and it trips on Live only. Very strange.
>299 ohms IR on all configurations (L/E, L/N, E/N), so no shorts.
Borrowed neutral? Nope. I wired the house 2 years ago. All been fine until last week. Also, putting the circuit on the other side of the board doesn't solve it.
Faulty RCD? Nope. Tests fine, and tried another new one just to make sure.
Anyone got any ideas?
Best regards,
E
