[QUOTE="supaev, post: 344489, member: 23659"] At the moment we have two RCD's on this circuit which causes nuisance tripping and there are no unprotected ways in the Main house CU. I have read about the various earthing systems but I am not sure what we have - just the usual domestic supply with a flat braded earth connection on the DNO fuse ., but this presumably won't impart much information to anybody. My electrician will be doing this and I expect he will export the house earth to the outhouse via the third inner of the SWA & bond this to the SWA armour as well as there is nothing metallic such as gas or water pipes in the outhouse. Re. using the outhouse CU main switch I thought these were just for occasional use for isolation purposes not for heavy use ( could be several times a day). [/QUOTE]
