I'm rewiring an old cottage where the joists have been exposed as a feature and plasterboard is being fitted between the joists which only leaves 50mm between the ceiling and the floorboards. The regulations require unarmoured cables run through the joists to be 'at least 50mm from top or bottom as appropriate'. It is of course impossible to achieve 50mm both above and below. What would a professional electrician do here? In theory it looks as though it has to be in conduit but I can't believe that this would actually happen?!
