upstairs lights tripping

[moneypenny]

I have just had some rewiring done to a ring main and an RCD fitted, got up the next morning to nothing but lights although only my freezer had been running all night and it wasn't that. The electrician suggested the sensor on my outside light tripped the RCD when it rained...... so that is disconnected untill I can get it relocated to a safer place.

Everything seemed to be ok until tonight when my upstairs lights tripped even though none of them were switched on. I'd had a shower shortly before and have recessed ceiling lights in the bathroom they are bathroom lights with a screw cap and were fitted by a qualified electrician, but could it just be possible that the steam from the shower prompted the trip and if so how can it be stopped. The lights worked fine all yesterday and are working now.

My electrician is a decent guy and said to call anytime there was a problem I know he will follow it up, I wasn't sure about the RCD... heard they could be a nuisance unless fitted at the time of a complete rewire but he assured me it would be ok so he is feeling a bit sick, and I'm beginning to feel a nuisance so I wondered if this is a possiblity (about the steam) I expect I'll find when if I run my shower again.

Any ideas

It could be any number of things and yr electrician should be the best person to find the cause.
I'm assuming he did the proper tests after doing the work but that may not have shown up some little nasties.

What you have described can sometimes be caused by something called a borrowed neutral. Yr sparky will know (or should know) what this means. In the meantime, keep a log of what is switched on or being used when the RCD trips. Sometimes you can narrow down the search by seeing that it always happens at the same time, or when a certain light is switched on or activated, etc.

Do tell us what he finds, always like to add to the knowledge base.

OK will do

Haven't been in touch with the electrician yet but I remembered after posting my query that before he left I asked him to show me how to remove the cover off my bathroom lights because I needed to clean out the trapped insects.

He said some rubber seals that should have been fitted hadn't, I didn't pay a lot of attention to it at the time.

Had a shower this am... kept it quick...the lights are still on, see how it goes.
