[QUOTE="Andy™, post: 451760, member: 2012"] 1: how do you know the one in the fuse box will trip? did you measure your Zs to ensure its within limits? the CSA will most likely be smaller. will this comply and be safe to carry the fault current long enough to allow the MCB to open? what about the nice new bit of cable that is also inadequately protected against overload? its also a reg that lamp holders are to be fused within specific ratings. easiest option would have been to use a fused spur... 2: forget about that one, not really an issue. its also very common to have a light on a socket circuit, properly wired and fed from a fused spur as usual, just because it works doesnt mean its safe [/QUOTE]
