Hello,
In a large Building that has a small sub station with switchgear, is it possible the Main Disconnect for the Bldg., is located outside in one of the cubicles? These are accesible by the Line crew, who work at the campus.
I may be wrong, but I always thought the Main Service Disconnect had to be in the Bldg. If it is allowed outside, away from the Bldg., then the first disconnect in the Bldg., would be considered a sub panel?
Thanks - Good Day

When you mention a campus it's hard to say. I'm in a refinery with numerous different building service configurations and our own fire department. When we build a building that is designed for occupancy and will be covered by the local municipal fire department we make sure we involve them. As long as they are happy with the disconnecting means and we meet the NEC 6 disconnect rule we have all sorts of situations. When you mention a campus it makes me wonder if some special arrangements exist.
