This thread doesn't really have a natural "home" as such, but as it concerns my home cinema, I thought I'd post it here.
My wife arrived home after dark last night with my son, to find the lights not working (save for the undercupboard lights in the kitchen and the cooker hood (oddly). The RCD had tripped. I rushed home from work, and through a process of elimination isolated the problem to the plugs in the living room. Further trial and error revealed it was some part of my home cinema - all plugged into a Tacima Mains Block.
I tried each item, and it seemed to be the blu-ray player so I left that unplugged and it all worked fine, then it tripped again. Then I noticed that the little plastic window in the Tacima had some condensation inside - I switched mains blocks, and that sorted it.
I'm not entirely sure how it happened, tho. We live in a Victorian terrace, and the mains block sits beside an exterior (uninsulated) wall, but is quite close to a radiator in a room which is well heated.
For those of you electicianly minded, I have two questions:
1. - will the Tacima be okay to use a again once it dries out?
2. - is it not a bit strange that the kitchen under-cupboard lights still function when the RCD trips? We had a new kitchen installed and had a terrible electician - I had to tell him what to do in a lot of circumstances (i.e. he placed plug sockets directly behind integrated appliances!), he then stormed off citing "I guessed it would take 2 days, and it's taken me 3 so I won't certify my works unless you pay me another £400" - we agreed a fixed price for the workks. He was fully part p registered. We did get someone else to certify, and he didn't pick up on that, strangely.
