When we had an extension 3 years ago some changes were made to the consumer unit and a new RCD was...
Just been on a "simple" job, changing 8 50w MR16 halogen downlights to (customer supplied) IKEA LED's (£3 each!).
Pulled out the 150W transformer that supplied the first set of 4 and changed these. The other transformer must be fixed into the ceiling void. I can't feel it and the void is full of...

Went to a job to check out a fault on an outhouse. Turns out that the outhouse is supplied via a 2.5mm T&E from the main house CU, which runs for several meters along an external wall (outside and unprotected) then disapears into a 50mm plastic pipe underground. The good bit is that at the other...
