Click to expand... Required by whom? To the best of my knowledge, it is not required by the NEC. I am assuming that you are referring to a door interlock disconnect, as would be required of a motor starter enclosure. Last edited: Feb 28, 2013

The panel is required to be on to store data in memory and come back on during power outages. I appreciate the reply. Thanks a lot. great web forum here.
