A quick question to my esteemed colleagues, do electrical intake cupboards in blocks of flats require FD30 or FD60 fire rated doors? Any reference to an authoritative document would be helpful - thanks.

Thanks Invictus, but I need a definitive answer, assuming there is one, and I need it fast.

oops same document, but they are talking about long term improvents to go to FD30

Thanks again guys, our FRAs state FD30s should be used for electrical intake cupboards. However this has been questioned by our term contractor who state they should be FD60s. Hence my query. Despite an exhaustive search I cannot find anything which explicitly refers to electrical intake cupboards and so I am of the opinion that FD30s are correct. With regards to British Standards, we do not have access to these so I cannot refer to them. I am currently looking at a package provided by BS which I will put to senior management at our next quarterly h&s meeting next week. This is a good case study why we need these standards - a little rainbow.

As a rough rule of thumb, I would say FD30S on most occasions Some buildings have fire compartment strategies to support horizontal evacuation or an engineered solution which may required a FD60. I have seen FD60s used when it is not possible to utilise 2 x FD30s on a staircase lobby. So unless there is a fire strategy or any other special reason - FD30 may well be ok
