New build CU entry and posistion

[magnoliafan89]

Visited a new build today with my spark to see his mate and having a look around came across this in the utility room loft.

Asides the horrendous entry i was under the impression from college that regs state a cu has now got to be made accessible and the switches of the breakers between 1350 and 1450..or is there exceptions to this?

Is that WIP or complete?

At a guess that's the Amdt 3 fire rating screwed...

Regarding the height I would fit a cu at high level, depending on the job. Sometimes it is specified to be lower like in an association new build but I wouldn't want a cu in the middle of a wall at light switch height in my house.

The loft location is a definite no no.

Name and shame the developer?

That's my understanding for a new build too, with the aim of being helpful to someone in a wheelchair. Don't think climbing a loft ladder is in the spirit of this

 

[magnoliafan89]

Well my guess was it was just temporary but i was curious if it was based on the entry so i asked but apparently that is final position

 

[robd]

Sorry didn't read the bit about the loft

What reg stated it needs to be between 1350 and 1450? I'm not saying your wrong I just did not know of this reg, I know they have to be accessible so obviously the loft us a very bad place.

building regs.

building regs.

I wish the muppets that write the rules would put them all in 1 document or at the VERY LEAST make a mention of the building regs ....

 

[Ian1981]

It’s only a recommendation in part M of the building regs I don’t think the CU height is set in stone.
It’s to the height of the circuit breakers.

Not one cable is secured to the back board.

easy, just nail through the middle. it's only an earth wire there.

thats nothing, ive been working in a building where windows are now jammed closed, some windows have smashed, doors wont open or close properly, cracks all over the walls, they obviously thought hiring a structural engineer wasnt worth the money

these are 4/5 floor flats, about 7 blocks altogether and all of them have problems

the electrical side of these buildings are actually ok though lol

HELD TOGETHER BY CABLE NO DOUBT.

That entry method is very poor and totally unnecessary. Aside from that the sharp edges present a possible danger...As to height there is no indication of what the height is!

 

[magnoliafan89]

Ive only ever taken the incoming through a gland and never had any other circuits go through the same entry with them...not that i could. But as this is what ive only ever been shown whats everyone elses opinions is it ok to send them all through the same entry or is it best to seperate the incoming with circuits?

 

[Rpa07]

I can only think that this is not finished yet and an intended 100x 50mm trunking enclosure is planned to tidy it up.
If that’s not the case, then it’s a pretty poor show. At least a grommet strip should be evident!
We can only speculate!

Apart from the picture and description of it in the loft.

Wonder how long the tails are? And why not use 2 round knock outs and grommets? - would've been quicker too.

Grommets cost money

My long range scanners tell me 600mm from top of ceiling joist to middle of breakers

 

[Cadgey123]

So 1350-1450mm board height, just because it’s not in BS7671, we still have to mount it there right? Or are you allowed to place them high out of reach etc

Details details...tut tut.

Think it depends on the context of the job and what is expected plus, as mentioned above, it is a recommendation and should be treated as such.

more down to what the building inspector will accept . if he insists on fitting a CU for dwarfs, then snow white and the 7 can live there.

That's a very interesting observation ..... and given that they are standard tails, I wonder how they are routed / protected?
