Bad Electrickery

Found during a standard building test. Had been in operation without complaint before we came across it; replaced the mains switch and cut the tails back.

Some of my friends asked me to check their consumer unit, as all the power had gone out. There was no power coming to the board, so we figured out the main fuse had blown. We took out the old one to have a look at it, and it turned out that there wasn’t a fuse at all, just a bit of corroded, burnt-looking bit of 2.5mm2 wrapped around the terminals.

Bad landlord.
