When do you mean by before? Immediately prior, the day before, an?
What do you do? Please explain.
Do you take someone's installation to pieces, discover a so-called reason not to change the CU, put it back together, and leave without charging?
Would a new CU not be better for all the other circuits - and the customer, of course?
Then, please, please, please tell us what you do.
Then we shall assume that you are ripping off the customers.
I consider putting the two lighting supplies on same MCB/RBCO/fuse is correcting the fault where some one in the past has split the circuit incorrectly.Why not just put them on the same MCB? Safer than leaving the shared neutral connection outside the DB and also better than leaving it disconnected.
I agree, but as you go on to mention, that would mean that there was only one lighting circuit for the whole house (albeit not really even an 'arguable issue' other than for stairs - i.e. hall & landing lights).I consider putting the two lighting supplies on same MCB/RBCO/fuse is correcting the fault where some one in the past has split the circuit incorrectly.
You may not agree, but BS7671 is pretty clear in saying that 'a circuit' is defined by a common OPD.However one does need to consider what will happen when there is a fault, although many seem to think a RCD does not make a circuit and it is the MCB which makes the circuit, I would not agree ...
I think probably not in terms of BS7671 definitions ....Could not the "O" refer to earth leakage current going over a particular limit?
Not really a silly game.. they're simply asking what you would do instead.Apologies for not playing your silly game if you need any more info see BS 7671 18TH EDITION Part 6. loads of text there there that you can pick holes in.
