I am fitting a new dual CU that comes with 10MCBs. For those that are unused is it acceptable to just leave them installed but switched off and identified as unused. Or should they be removed and replaced with blanks?
IMHO it would only amount to 'Bad practice' if a copy of circuit details were not left adjacent to board highlighting the fact that (X) breaker was a unused way, this was my whole point of my post regarding regs for circuit identification ( Which someone got arsy with me for ), it's important that an unskilled person knows what to switch of or reset

ok i understand the regs, but even without the all important chart, the customer will re-set the breaker that had tripped(would be identified anyway), and if anyone working on the board in the future couldnt identify a spare circuit then, well they souldnt even be there.IMHO it would only amount to 'Bad practice' if a copy of circuit details were not left adjacent to board highlighting the fact that (X) breaker was a unused way, this was my whole point of my post regarding regs for circuit identification ( Which someone got arsy with me for ), it's important that an unskilled person knows what to switch of or reset

I take them out and put decent blanks in, i only fit Hager boards so I can always get hold of good blanks. Personally I think It's rough to leave unused MCB's in. If your concerned about the customer having paid for them then give them to the customer instead of leaving them in the board.
The customer knows whats what from the clear labelling on the CU
I look at it this way way if a customer gets you in to fit a CU they aint going to start running new circuits and fitting a MCB I had a customer tell me he got a shower fitted a year after I fitted the CU the company made a big deal about electrical safety so when they sent their "spark" in he was chuffed that there was RCD protection plus spare MCBs for the shower and electric towel railSo the customer can try and fit them himself at a later date , which is much much safer ???
I think the discussion around this trivial subject is getting a bit silly now.
Leave them in , dont leave them in , its not bad practice either way , BS7671 doesnt care either way.
A bit of perspective and common sense serves better than some of the daft claims being made.
It only takes 5 mins to copy across your data from the EIC to another chart, or you could just copy the cert test pages and leave them there,is anyone gonna die if you don't ? no of course not, the customer couldn't care less ? well perhaps they don't but thats no excuse for that little bit of extra effort is it ?

jog onIt is essemtial in commercial/industrial etc. and most jobs won't get signed of till the clip frames are on the wall, always a last minute apprentice job!
Don't really seee the need on domestic though, I have never seen a house with one and I have tested a lot! However with a lot of sparks doing paperwork on the PC now, would it really take more then 5 mins to make one up and at least give it to the customer with their invoice? (p.s. I dont work for myself, so tell me to jog on if you want!)
If the fuseboard labelling isn't clear, I can't help myself but to correct it after finishing testing!, even if that means tippex out!
Forgot to mention though, although I don't leave MCB's in, I don't really care or think its a regulation or even a 'best practise issue' Just a minor point!
well said biff, its easy to get cought up in these discussions, sorry for my part, ill keep leaving them in, and if people wana leave em out good on ya,
........ everyone has the " well i had a customer who did this , that and the other" type stories - it doesnt prove anything either way to be honest.
