Lol. Six are labelled as they were when I moved in, the other two don't appear to be in use as far as I can tell. The shed appears to be wired into the kitchen sockets much for some reason that I can't ascertain - that's the mcb that turns it off but it also turns off the freezer which is pretty annoying as next job is to replace the shed! Will need to work out how to move it to one of the two unused ones - could there be a reason why the guy didn't put it straight into one of those in the first place?
