What fuse/circuit breaker do you put in the fuse panel with radial wiring? It's got to cope with the largest appliance you'll put on that circuit. With British plugs, a low-current device such as a lamp should have a 3 amp fuse, so it blows before the thinner 5A-rated wiring to the lamp melts. The problem with British plugs though is the rectangular pins. Mechanically, it's simpler to get a good large contact surface area with a circular pin in a circular socket. You do sometimes come across UK sockets which have been slightly damaged and get hot because the contact resistance is no longer negligible.
