Bizarre reason for RCD nuisance tripping...
While RCD nuisance tripping continues to occupy our minds I thought this
piece, posted in the IEE/IET Wiring Regs Web forum this morning might amuse... The case I was thinking about was a little old lady who lived alone. I had rewired the cottage (out in the sticks) and replaced an old voltage operated CB with an RCD as part of the works. Job done, I was alarmed to get a constant series of phone calls from the son indicating the RCD had tripped. This happened during the night and every time the lady got up the power was off. It turned out she was in the habit of getting into bed with the lights turned off and reaching for her bedside lamp which had no lamp in it. In went the fingers - quick jolt and she claimed she felt much better. She had done this for years but since the RCD install, off went the power. Bedroom was dark so not noticed until the following am. Not the sort of fault you can predict - and the old lady wasn't admitting to her actions - she instinctivley knew it was "wrong" but carried on regardless, convinced that it did her heart and circulation some good.
