[QUOTE="davetheglitz, post: 12947, member: 173"] Just a thought - but would it be possible to just replace the main switch in each board with an RCD - or (if the boards already have an RCD) to move everything apart from the lights on to the RCD side and fit an RCBO for the lights. There is an arguement here that the circuits for the whole installation are segregated by virtue of being on a separate CU - and if all circuits are RCD protected it obeys the major principal of the 17th as far as electrical safety goes. My concerns are a bit more fundemental and I realise I don't know the answers even after consulting the good book! 1) As the property is sub divided it is my understanding that main bonding would need to be in place for each let - which could be a lot of extra work. Is that correct? 2) As that these are business lets - there may be a lot of computers - so would the RCD's be subject to tripping? 3) As these are business lets can you consider that the people are employees under the instruction of a skilled person - in which case could the RCDs be upped to 100mA? Hope someone here has more answers than questions! Cheers [/QUOTE]
