Hi all,
I'm having a problem with a newly installed RCBO. Having made alterations to a lighting circuit in a bathroom I recommended to the builder that the MCB on a 16th edition consumer unit on the non-rcd side be replaced with an RCBO as per 17th edition. I completed continuity ok, insulation resistance 0.54, not great! Attempted to turn on RCBO and it won’t turn on. Fault on the wiring. I hate fault finding. Why won't it just work. I put the MCB back no problems. Tomorrow I have to do the usual thing and explain to the customer why I emptied there linen cupboard to install an RCBO which they haven’t asked for and that I have no idea how long it will take to resolve the issue. What concerns me is that if It were a borrowed neutral this would allow the rcbo to be turned on but trip when under load? The rcbo not turning on is disconcerning.
