Did I or did I not ask you to double-check that the socket was on? Now I've driven 15 miles, what have we found?

Re: Primarily Fuses.

No its to protect the house from the flex to the plugged in device. The socket is 13A but the ringmain is fused at 30A or MCBed at 32A. If your low powered device with say 1mm2 flex develops a fault and it isn't protected by a 3A plugtop fuse, then the flex gets hot enough to burn. Likewise all other flex sizes should have the correct size fuse up to 13A. Since the ringmain itself has 2 paths back to the distribution point the house wiring doesn't even get warm unless you are doing something (hopefully) unintentended like simultaneously drawing 3KW from 2 other sockets on the same ring at the same time as your device has a fault. Even then it should only get warm not hot enough to start a fire.
