Rcd not tripping

[Engineer54]

Not sure that having all the circuits on 1 rcd in an annexe is a particularly good idea!

Not sure it complies either!! Surely with just 4 circuits, it would have been better to have used RCBO's. You can get an all RCBO CU (4 RCBO's) with a couple of spare ways (6 way CU) for £53.30 (plus vat) .....And you would have known straight away what circuit was playing up, without affecting any of the other circuits!! lol!!

Take out mcb's rcd's and start again using rcbo's
