The exception to 690.14 (C)(1) states installations that comply with 690.31(E) shall be permitted to have the disconnecting means located remote from the point of entry of the system conductors. (I have a commercial customer that wants the PV disconnect by the array (about 100 feet away) versus on their new building wall at the point of entry of the PV conductors which will end on an 80 AMP CB inside an existing 400 AMP panelboard - load-side connection using the 120% rule.)
I am not sure that 690.31(E) applies to my situation? 690.31(E) empathize DC PV connections(however, it also includes .."and output circuits inside a building"). I my configuration the PV conductors that enter the building, on their way to the 400AMP panelboard, will be AC as they are the output from the inverters at the array. I can put the PV AC conductors in continuous EMT from the outside building wall to the 400AMP panelboard and follow the other requirements of 690.31(E). Is 690.31(E) an acceptable exception for me to remotely locate the PV disconnect? The local Utility Company has given approval for the remote disconnect but I have not passed it by the local inspector, want to do my homework first.
