I have an application where I have been requested to wire a 208\120 Volt, 3 Phase, Standby Generator system and ATS (Non Service Entrance Rated). I am planning on installing a dedicated Standby Electrical panel that will handle the requested loads during a power outage. One of the loads requested is feeding a 50 Amp circuit to a separate building, (same owners), that is 60' away, with an existing underground 2 1\2" conduit between the buildings, but this building has its own utility service. I see in the NEC 230.2, that only one service is allowed to a building or structure, unless you read the exceptions. But this isn't considered a "service", but a branch circuit? Is this branch circuit allowed to the secondary building by the NEC? The secondary building would be fed from the Main building's service, regardless if the standby generator is running or not, because the ATS would transfer the power on through in normal situations. Is this installation allowed by the NEC?
