Hi everyone,

There isn't enough room for all the distribution panels in the electrical room. Are any other utility rooms allowed to house these panels (and ATS's)?
for example, there is a fuel oil room adjacent to the elec room, which would be very convenient.
 
Questions about "electrical rooms" and things like what can or can't be in them seem to come up pretty frequently here.

NEC doesn't use the term "electrical room". In fact in a search through electronic version for "electrical room" I only come up with one result and it was in 728.5 and merely mentioned electrical room as one type of room that applied for topic of what that section was about.

Closest thing to what most people are inquiring about when they say electrical room is what is covered in 110.26, but that section does not dedicate an entire room to electrical equipment just space about the electrical equipment in any location.

Are these NEC 700/701/702 ATSs? Is this Level 1 or 2 according to NFPA 110?

A fuel oil room likely lands you in a hazardous location. This being adjacent to an electrical room may even have the electrical room within a classified area. What is the application for this building?

Exception may be if your equipment is not lockable - then a room may be required to restrict access to only qualified persons.

Fuel oil (such as K1, K2 kerosene) doesn't have low enough flash point to create hazardous location.
