I saw in 2023 they had to add a rule that panelboards can not be installed face up because apparently someone did that at a laundromat. There’s no rule against installing them face down though….. We can’t make enough NEC rules to stop stupid.

If you turn the picture right side up, and, picture it in the side of a hill instead of the ground it gets much more tolerable. :)

480V submersible pump, on the top of the well they installed a 30A 600V NEMA type 1 GE safety switch, this would also be in my opinion a residential install supplies a double wide mfg home, and a AG shop which is where the 480 came from, there is a MIL unit attached to the shop & that was the only place I ever have seen 277V lighting in a residence, gone now. Everyone gets to see strange things, some worse then others.

The face up rule was in 2020 and 2023 added a face down rule.
408.43 Panelboard Orientation.
Panelboards shall not be installed in the face-up or face-down position.

Imagine telling a customer “hey we can install that panel board suspended with threaded rod face down from the ceiling if you hire me before my state adopts the 2023 NEC!”

Working space has nothing to do with fuses or other types of OCPD. I require 110.26(A) for all disconnects as those are very likely to have the voltage checked while they are energized.

WA state has an amendment that disconnects without fuses or breakers doesn't need to comply with 110.26. They treat it like a single pole switch. So there are some places that view this as an important factor. I think that 3r isn't enough for a bellow grade install like that without a structure.
