Hello,
Been asked to do some work in a building consisting of 5 flats which are being redeveloped. At the minute, the distribution circuits to each flat consist of a 60a switch fuse with a 10mm CPC and 25mm line and neutral cables usually used as meter tails.
They are all in trunking and the developers want them either buried in the wall or boxed in.
First question, are "meter tails" OK to be used for distribution circuits?
Second question, I guess they need to be RCD protected - what is the best way of achieving this when each flat will have it's own 30ma RCD. A time delayed 100ma RCD? (which from my interpretation wouldn't meet the requirements, but neither would a 30ma RCD (discrimination) or omitting an RCD on the distribution circuits).
Thanks a lot for your help!!
