Hello all,
House is 22 years old. Wiring probably not done brilliantly to start. This is the second ceiling light in a small room I use as an office. Was child's bedroom and I cannot state 100% if this light ever worked.
Anyway, I fitted two new Habitat lights, ditching horrid Chinese block...

I was doing an EICR today on a bog standard terraced house, and as part of that was checking the fuse ratings in the boiler FCU etc. (always do this as often people can't be bothered to swap out the 13amp fuse). Anyway, found the boiler FCU was fitted with a 1amp fuse, a spur for a built-in...
Just fitted a light for someone, one of these 5 way 12V 20w things with 105VA transformer in the base.
Put 1 lamp in and it lit very dimly, so checked the transformer and was getting nothing through it. Put in the other 4 lamps and they all worked perfectly.
Any thoughts on probable cause of...

Hi guys! :)
I have kind of a dumb question and so I searched for electricity related forums and found this one. Sorry if I sound really silly, but here goes:
Can anyone please tell me why are these weird box things so common and what do they actually do?? :(

First visit here so hi everyone.
My problem is I have just gone to do add a few sockets for someone and upgrade the fuse board. Done some basic checks first and discovered an existing ring main had a very high zs (3.4). Checked the Ze and was fine (.2 for tns). Assumed there would be a dodgy...
In the cold mornings as the sun rises, there is condensation on my panels. I noticed a weird effect on my shaded panel and took a pic. Is this as expected?
