[QUOTE="binky, post: 482486, member: 490"] computer equipment has a lot of 'smoothing protection' built in, which in short chucks a bit of leccy down the earth cable. 1 PC isn't a problem, but multiple PCs and other equipment will mean that the RCD sees this as a fault, and if that RCD is shared with other circuits in the house you will have earth leakage from other appliances, and constant problems, so there are 2 ways to go:- 1/ change MCBs (circuit breakers) and RCD if shared across multile circuits for RCBOs which combine both functions into 1 unit. This effectively gives you an RCD per circuit so is more reliable 2/ install a non-rcd protected circuit for your computer equipment, or protect it with something like a 100mA RCD - I prefer no RCDs at all, but there are constraints on cable runs using this method, and no socket should be anywhere likely to be used for plugging in your lawn mower, or other portable equipment to be used outdoors. The later point can be overcome by using RCD protected sockets. (you could also take circuit off RCD and use RCD sockets depending on cable runs). [/QUOTE]
