Hi All

Hoping someone will be able to help.

We're currently working on an office refurb and looking the move the electric meter and cut-out. The supply is around 70kVA.

We're looking to move it to a circulation space and I have been looking to see what current regs say regarding electric supplies being on escape routes.

I thought there might be something in Approved Document B but I couldn't see anything. Is it something that should be picked up in the FRA?

I welcome your thoughts!

A bit more information required.
Is the intention to have the equipment exposed in the circulation area? (Unlikely I would suspect)
If not, how is it to be enclosed and what fire rating is the enclosure going to have? - Even 2 layers of Plasterboard changes the fire spread characterisitcs.
If this is a fire escape, how high?
This needs a lot of input from many people before you go ahead. I assume you are working with all the relevant parties to plan this as there are many things (some not obvious) to take into account. I would avoid this if possible, as the requirements will be much more onerous than in a properly designed plant room.
I may seem a stupid question, but where is this? The regulations vary between Engalnd, Scotland, Wales and Northern Ireland.

Hi Dave

apologies for the lack of details.

The equipment would have to have some form of enclosure in to prevent interference by anyone that passes. As I was just looking into the feasibility of moving it to this location, the fire rating of the enclosure hasn't been discussed. I would imagine it would have to be a 60 minute fire rating if it was allowed to be installed in the proposed location.

This area forms the landing between stairwells, with the space measuring around 2500mm x 1800mm, and both stairwells being at the same end of this area.

And I should've said that this was in England.

I posted this question to see if it was a no-go before I submitted the application to UKPN for a service alteration. Also, if it was a non-starter I could go back to the architect to start discussing alternative solutions. I'm working with the design team as well as the DNO but in terms of the less obvious things to take into account, I would welcome any advice.

Thanks!

You need to ask UKPN. We would say on a solid wall, within 1.5m of an external door.

Regards,

Alan.

Thanks for the reply Alan.

I've put the application in but I suspect it'll be knocked back, so we're working on alternative solutions.

Thanks

Other suggestions are an outside meter box, or a suitably sized cupboard built into / against a wall outside the building. I can think of several instances where a brick or blockwork cupboard has been constructed.

Regards,

Alan.

Can someone tell me what UKPN stands for? I'm guessing UK Power Network provider? am I far off? Thanks.

OMS I love that. I'm going to have to call them sweet 'n sour from now on.

Spoke to sweet 'n' sour and they are going to come out to site to see what the options are.
