Electricity cupboard 30min fire resistance

[Neil t]

Hi, 

 

I've been asked to make a 30 minute fire resistant cupboard that houses the electric meters for a house that's been converted into flats. 

Could i make the frame/boxing and the doors out of FR MDF Class B - which gives a 60 minute fire rating.

and fit intumescent strip around the doors?

Cant fit a standard FD30 with stud work and plasterboard as the front door would not open due to the thickness of build up. Can only get away with 18/25 mm build up.

Also a lot of the meters are up at ceiling height so doors need to be light enough to open easily.

 Cheers

Neil

Using this would be simpler https://envirograf.com/product/electrical-consumer-unit-and-distribution-board-fire-protection-system/

Thanks for your reply, yes agree that would be easy.

Only thing is there is other stuff that they want hidden from view - gas meters, water valves, electrical trunking and the mains armored cable, telephone distribution.

So i need to make a unit for it all anyway, so would the fr mdf euro class B, be sufficient?

Thanks

If the finish construction meets an half hour standard closing the meter/ancillaries and satisfiers' building control it should be satisfactory.
