3 Phase power keeps on tripping

Daveh36: Good evening Sir. Had you thought (hoped or wished?) I'd gone away

Just wondered if you had any further developments if only to inform more on the problem? I need things to think about 'cos my wife is back in hospital.

Oh dear that's not good hope all is ok. On the tripping front though since I replaced the mccb again and got DNO to monitor incoming supply things seem to have settled down (famous last words). I'm thinking they had an issue with the supply but are not for telling me. Fingers crossed for now as it's not gone off in week given my hair chance to grow back haha

It sounds like a head scratcher indeed.

If it continues to trip, check if there is a Telecom Cabin on the rooftop somewhere. As these are normally full of AC-DC rectifiers and PSUs.

Failing that, get the LL to have an Electrical Installation Condition Report on the subs and LL services.

Daveh36: Has this problem been resolved or 'simply gone away'? Be interested to know.
