[QUOTE="spinlondon, post: 75396, member: 3394"] All circuits in a TT installation must be protected with at least a 100mA RCD. All socket outlets below 20A must be protected by at least 30mA RCD. All circuits with cables buried less than 50mm in walls must be protected by at least 30mA RCD. All circuits in bathroom must be protected by at least 30mA RCD. You could have an installation where the cabling is all in surface trunking, the sockets and bathroom circuits would have to be on 30mA RCDs, with all the other circuits on the 100mA main switch. You are required by the Regs. to consider the effects of having more than one circuit on an RCD. There is no requirement to actually place all circuits on separate RCDs. [/QUOTE]
