Combination electrical/mechanical room

[lfloyd]

I have a plan with an electrical room with a 1200 amp 480 volt MDP and transformer that exits through a cased opening into a mechanical room with a 500,000 BTU boiler and then out a door into a parts room for a repair garage. The building is non-sprinklered and I was going to require a one hour separation for the whole thing. The combined areas are only 350sf and provides a clear egress from the electrical equipment into the mechanical area.
I don't like the idea of combining the two rooms but don't know of any code that would disallow it.
Am I missing anything?

This is frequently done. To my knowledge there are no IBC codes that requre any fire rating for the room. As long as you provide the require clearances about the gear per 110.26 then you are good to go.

Historically this can be a challenge to coordinate the location of electric gear with ductwork.
