We have these. Four three-phase disconnects. 1 is 100A, 2-4 are 80A. Coming off the other 400A panel, almost entirely unused. Hey look, 60A 2P&G! (Subtopic: Who uses those, and for what?) Now, onto the disconnect: Here is a close up, and further away, please note Charc Hand. So, what connector is this? Hint: It has Hubbell written on the side.
