Comsumer unit - upstairs/downstairs ring mains

taconite1 · Sep 26, 2023

Hello,

I bought a new build and noticed the upstairs MCB is controlling some sockets on the opposite floor, so if I flick the upstairs MCB it's also switching off a socket downstairs (I think it's a spur) in addition to all the ones upstairs

Is there anything within 7671 that states this is wrong?

I asked the contactor on site and they said it can be re-wired but it's down to my prefrence. Is this correct? Surely the regs have something to say on this.

P.S this same contractor didn't earth some of the metal faceplate light switches (including backbox) - so I don't trust them at all. Despite having a NIC form filled in and signed by two qualifed electricans!!

Few questions from me

Is a "DOMESTIC ELECTRICAL INSTALLATION CERTIFICATE" the same as the "building regulations certificate of compliance"?
if they move a socket from the ring main upstairs to downstairs do i need a new DOMESTIC ELECTRICAL INSTALLATION CERTIFICATE?
I've been around and counted the sockets and it doesn't match up to the quantities refered to on the DOMESTIC ELECTRICAL INSTALLATION CERTIFICATE - another problem?

I have come across this many times..."If I sacked all the rubbish workmen, I'd have nobody to build houses"...but these houses are not cheap! No, they are very overpriced, but built cheaply to maximise profit.
That pic of the wiring is just an example of awful workmanship. I'm not an electrician but I'd be ashamed of myself if I wired stuff like that. OK< some of my stuff might be less than perfect, but I'd be happy for someone to take off some faceplates and try to find real fault. It's not really rocket-science to wire a socket, but it's a proper skill to do it properly, and if you can't do it, don't pretend that you can (and charge good money for shoddy work).
To the OP, if your house is covered by the NHBC scheme you could try a complaint to them...but it's a waste of time.
