[QUOTE="ADS, post: 206177, member: 7231"] Assuming the job is not in Scotland, Approved Document P, Section 2, [B]2.1[/B] Where any electrical installation work is classified as an extension, the addition & alteration work [B]must[/B] include: [B]a)[/B] such works on the existing fixed electrical installation in the building as are necessary to enable..... the addition/alteration (the extension) ; the circuits which feed it; the protective measures & the relevant earthing and bonding systems.......... ....[B]to meet the requirements[/B] AND.... [B]B)[/B] Establishing that the mains supply equipment is suitable. So all four items listed above have to meet the requirements of the current regs........the 100 mA up-front RCD doesn't, and neither will a RCD fused spur......what about RCD protection for the rest of the circuit? :) [/QUOTE]
