[QUOTE="ProDave, post: 514110, member: 6969"] Why a no no? My own house has a 16mm feed from the meter box to the CU fed from a switch fuse with an 80A fuse in it. The max demand is only a small fraction of that. Irrespective of size, it there is more than 3M from meter to CU there should be some form of over current protection, not just the DNO's fuse.
