that's appropriate for the appliance at the other end. You can buy the special 5 amp fuses that go in those socket strips from electronics suppliers. I bought 100 of them, and have added fixing stupid electricity sockets to fixing IT equipment. What really annoys me is why they felt the need to fuse every outlet. The laws of physics say one can chain as many UK 13A extension blocks as one wants to. The 13 amp fuse on the first one will blow (and disconnect the whole chain) if the total current drain of all appliances connected to the string exceeds the 13 Amps at which all such blocks are rated. Not much risk of that with IT stuff. OTOH there are some laser printers that can take out a 5 amp fuse, since they take &gt;5A for a few seconds while heating up from cold. And if there were no 13 amp fuse, four times five amps is 20 amps, which is an overload condition for a 13 amp plug! Re: No fair As I understand it, UK power sockets are wired in a loop, with both ends of the loop terminating at the breaker panel. This was done to save copper - each outlet is, in effect, fed by 2 sets of wires, and so you have double the copper free of charge (no pun intended). However, that means that opening a fuse on one end of the loop will NOT disconnect the rest of the loop
