Hi all, first post. I'm planning a full rewire (i used to be on the tools and have my C&G part 1&2 level 3 NVQ and the old 16th Ed, did fail the 2391 ) so I do have an understanding of the 17th ed after following blogs etc etc. Now my understanding is that as the house is not part M modified or built I've no requirement to apply the socket and switch specification as per the height from the floor correct????? As far as the CU is concerned I'm just fitting all RCBOs at £10 each for new ones off of flea bay which I think is a cracking price. Anyway I would appreciate your input, thanks Dave
