Looking at Article 695 it looks like my only option is to either run the conductors outside the building or under the floor slab to the fire pump. In my case it would be easier to run outside the building I think.
The service comes in at one end of the building (the meter is inside the building in an electric room). The "service" for the fire pump is connected to the meter before the main disconnect (circuit breaker). The fire pump "service" will be instaled in conduit out the wall and along the outside of the building to the fire pump room (which is at the other end of the building). The disconnect and circuit breaker for the fire pump are at the fire pump.
Anything wrong with this scenerio?
