Every electrician who's come to this house seems to have done his own little bit of wiring without ever marking the fuses to which he's been connecting his latest handiwork. It took me all morning to trace everything back to their respective fuses.
I've drawn up a little sketch of each room's layout, with each powerpoint and light referenced back to its respective fuse number, and pasted it inside the meterbox.
Fuse # 6 not only mixes powerpoints and ceiling lights but does so in a great profusion across the whole house: seven powerpoints, both upstairs and downstairs as well as outside, and fifteen lights, but this time only downstairs and outside.
To make the whole thing 'legal', I ought to call in an electrician again to separate the powerpoint and lights circuits on Fuse # 6 - if it can be done without pulling half the house down!
