No space for new CU.

[OldskoolUpNorth]

Afternoon all,

Just got back from inspecting a domestic that is having a new CU installed.

Thing is, the DNO in all their wisdom have been out and fitted a posh new isolator as requested, FOR FREE, and put it in the only space big enough for a 17th board.

Now to the question,

Can a CU be mounted vertically?? i.e. On it's side. it's the only way it'll go in, and I don't think the guy will go for RCBOs and a smaller board just wi the cost of em.

Anybody ever fitted a CU vertical? or is it a big no-no.

Thanks as always.

yes....as long as the IP rating is not compromised and its mounted securely...then why not?....

 

[sparks1973]

any labeling would of course have to be readable by the client/user......

I think I would just move the isolator. Anybody who looks at a CSU on its side, whether its right or wrong, is going to criticize it!

It would be a lot easier drew but I don't cut DNO applied seals, I know people do but thats up to them.

Otherwise I'd just of removed the main cut out in the first place.

so is it still compliant to have it on its side?...yes or no Drew?...

 

[telectrix]

it's compliant. think of a 3 phase boars, all the protective devices are mounted horizontally.

Unless the instructions for the CU state anything regarding positioning? Daz

It's acceptable to mount a consumer unit vertically as long as the main switch & circuit breaker 'on/off' positions are easily identifiable and circuit identification corresponds to the relevant OCPD.

According to Elecsa technical.

As mentioned, the main things are IP rating, function and identification. I would never do it, but I can't see a reason not to, as long as the above is ok.

Wont all the electric fall out if its on the side? :thinking2:

The other option is to fit a 2 tier board in again its a space issue.

 

[trev]

It should just settle on what becomes the bottom of the CU mate but the bus bar will suck it up to the MCBs. Caplliary action you know
