200 amp Distribution panel in Boiler Room

(OP)
Can a 200 amp distribution panel be located in a boiler room?  The room will not get hotter than max 120-deg F.
thanks,

RE: 200 amp Distribution panel in Boiler Room

1.  Electrical panel requires a dedicated space including space above it.  See NEC 110.26.  

2.  Ambient temp of 120 deg F would require de-rating of all the breakers in the panelboard and panel bus rating.  Panelboards built to UL and NEMA standards are rated for a maximum ambient of 40 deg C, which is 104 deg F.
