[QUOTE="Paulkk, post: 394073, member: 26359"] Hi All First post here so please go gently. I've recently moved to a new build house and the developer has kindly installed a single double socket and light fitting in the detached (6.5M x6.5M <1.5M from the house) double garage. - the general layout is this 20mcb on the RCD protected side of the house CU delivering power to a CU in the garage via 10mm armoured buried cable. - The garage CU has a 16a mcb for power and 6 a for lighting and seperate RCD. As I don't want flexes trailing everywhere I want to convenience of 2 x double sockets on the back wall and 2 x double sockets on each side wall and maybe one in the ceiling so seven in all. Should I run them as a radial off the existing 16a mcb or run a ring back to the garage CU? If I run a ring my understanding is I would then need a 32a mcb but given the house CU has a 20a one should I plan on changing the garage one, the house one or neither? My plan is to site the sockets myself and cable them but to get a proper sparky to terminate the cables to the garage CU and do appropriate testing (the developers are still on site so they may do this for me). Buying the right stuff in the first place will just save me time and money Any advice would be most appreciated Many thanks Paul [/QUOTE]
