During recent works our electrician noticed that half of the power points in our house are on a radial. The radial was originally on a 32amp fuse and for safety reasons the electrician has fitted a 20amp fuse, However, he pointed out that anything in excess of 20amps could trip the fuse. I notice the socket to our computer has a 13amp fuse. Do we need to avoid using sockets that are in excess of 20amps, or does it relate more to the number of kilowatts used at a time? We have had works carried out and are about to move back in to the part of the house where the radial is.
