I arrived at a school today with only two keys. One for the main gate and one for the new mains electrical room. The new supply is not yet there.
Bugger. The mains room has not got a 230V socket. A quick look around the empty caretakers house discovered that it did not have an external cut out so I could not pinch a feed from there.
So I made a phone call and had a full set of cordless power tools dropped off. Whilst the tools were delivered I made up a temporary socket.

make things worse the light had pushfit terminals that only took two cables per terminal and was wired in singles. The first neutral I disconnected was the incoming one:-)Adam
