I have an outbuilding that a solar array is being installed on with the inverter located in the same building. I want to install the solar back feed breaker in the sub panel in the outbuilding. Two scenarios : 1, the sub panel has a main in it as well as a breaker in the House panel that is feeding it. 2 : the sub panel is a main lug that is being fed from a breaker in the House panel. Question - what is classified as the "true" back feed breaker and how is the calculation done (code articles would help) ? I am dealing with a very confused inspector
Thank you
