Me and my partner have been debating the code compliance of the following PV ac disconnect scenario.
On a single family dwelling there is a standard 200 amp overhead service coming into a meter pan, exiting the meter pan, and terminating on a main breaker panel inside the house. We are back feeding the service with lets say a 10kw pv system. This install requires a line side tap so as not to exceed the 200amp bus rating. In our location the utility company requires a disconnect installed outside near the meter location to disrupt the ac coming from the inverter. To kill 2 birds with 1 stone we perform the line side tap below the meter outside and use a fuseable disconnect thus satisfying the utility company and providing tap protection. My partner claims this is a violation citing 230.72, all service disconnects must be grouped. My arguement is that this is a new service and can be located in a different place as long as there is signage, 230.2(A)(5) and 230.2(E). Anyone want to pick a side???
