Is there a requirement in the code like in article 550 that addresses a maximum distance from the building to have a disconnect? I would like to have a pole mounted service and then feed the building which is 200' away there will be a main breaker in the panel closet to the point of entrance inside the building. Basically service on pole and feeder to building, service at building treated as sub-panel with isolated neutral,4 wire and also a GES. Or in other words how far can the service disconnecting means be from the building
