Mains wired smoke / heat / CO detector question

Cheers, you're just trolling now

Take Buzz with a pinch of salt, he's often out on day release and sometimes he manages to avoid his carer and gets online.

Thanks everyone.

Just had a chat with electrician and explained what building control said about not needing mains powered sensors. He's said to check with main builder and the building inspector, so will do that.

He also says because the consumer unit is being moved it needs to adhere to updated regs, so we need a new "gen-18 unit" and "these are a bit more pricey than they used to be". - Can anyone confirm if this is the case?

Losing the will a bit here, phew.

Hmmm. How far is CU moving, and are any of the circuits being extended?

CU is moving about 6ft up the wall it's currently fixed to, mains cable runs up the same wall.

We've not anticipated any circuits being extended as the current rooms already have lights, sockets, oven etc. circuits in them. There will be some moving of wiring but doubt there'll be additional circuits needed. There are 3 spare module slots in the current CU if that makes any difference.

Buzz - I know you're just messing mate but is there any chance you could answer the questions I've asked and genuinely give your expert view on this situation?

IMO then is just moving an enclosure & I would suggest comes under maintenance, & does not warrant latest. In such a scenario, I would contact my Scheme for guidance, but as I'm no longer in a Scheme I can't.

 

[buzzlightyear]

no ,trying to help you ,if you having any work done then the only people to give you advise this your local building control .

I put that in post #15 for you .

 

[buzzlightyear]

its about time the government need to put on tv about part p, so people like you ,would under stand how things work ,your building inspector and builder should advised you straight away .and the spark that doing the job .

that is total Bollox. re-siting a perfectly good CU is compliant.

a "gen 18 unit " is just the same gubbins in a metal box.

If the CU is being moved 6ft up the wall, its not going to be at a regulation height, ie it'll be too near the ceiling. You'll need steps to reset a breaker.

Nothing wrong with using battery powered smokes with radiolink interconnect from Aico for example. More expensive to buy, but saving time on install. (4 detectors, 30 minutes tops) and theres no cables to run under floors etc. No damage to existing decoration.

The only thing not regulation with the board is that its plastic. Buy a metal one yourself and use the existing breakers. Just has to be the same make of board.

Is this electrician already doing work for you or is there a chance of getting other quotes?

 

[telectrix]

regulation height for CUs ( along with dwarf accessible light switches) applies ony to new builds.

See post #11 mate. I'd already explained that I'd spoken to building control and they'd contradicted the electrician.

I can only go on what I'm told up-front so if I get an updated quote just before work starts with an unexpected extra £820 for the extra electrical work I'm well within my rights to question that. Good job I did too, eh, as if I didn't I wouldn't be here getting good advice from people who know a bit more than I do.

What I've worked out today is that there is a disconnect between electrician and the builder and inspector. I'll find out tomorrow morning exactly what the building inspector expectations are in terms of mains wired sensors.

Your comments throughout have added nothing of value but the guy trying to get the advice got it from those that would rather be helpful. Sorry if you've taken some kind of offence early on in this thread, I'm only asking questions mate....
