I am trying to understand the definition of "commercial building" as it used in this section. Does this mean any construction other than dwelling units is considered commercial? In particular, my project is at a local community college in which we are adding internally lit signs to identify building entrances at 12 locations. It is an existing building so I'm trying to determine if 12 separate dedicated circuits are required per this article or if I can tag onto existing circuits at each location.

The way I read it, you can have a single branch circuit that ?supplies no other load? than the ?at least one outlet . . . for sign . . . use.? In other words, yes you can have one branch circuit supplying 12 signs, so long as there are no other loads than the 12 signs.

I agree with Charlie, but I don't think a community college would be a "commercial" building. Reading the handbook commentary (I know its just an opinion) I see two things that don't seem to apply. One is the need to use signs to attract customers. I don't think community colleges get many students to sign up by putting up lighted signs at the entrance. The other thing mentioned is the fact that new tennants may move into and out of commercial buildings, addding and removing signs as they go. I don't see this in a college either.
I would suggest you ask the AHJ.
