30"

Typically, if it's easily removable then it's a cover not a door. You measure the working space of a covered enclosure after removing the cover completely. You measure the working space of a door enclosure with the door fully open.

I don't believe the 90 applies to operating that sort of door. It applies when you remove the whole cover for service.

If you remove the cover there is no need for a 90 degree opening requirement, cover should be laying wherever you set it.

Is there a minimum depth requirement for a door that does not expose you to live parts when opened?

Good design practice may consider this, but I don't believe it is a code problem.

I have no problem with that install.

I don't see any problem either. You have to remove the door/cover in order to remove the deadfront to even access live parts.

I don't see a problem either.

110.26(A)(2), last sentence...

In all cases, the work space shall permit at least a 90 degree
opening of equipment doors or hinged panels.

I don't think that is a violation either. But if that cover is able to be turned 180 degrees so the hinge is on other side I would likely have installed it that way. It looks like it very possibly could be attached either way.

A removable cover would be >90 since it's effectively opened 360.
Depth of door? The measure point is the opening of the enclosure the live parts are contained in.

110.26(A)(2), last sentence...

Presumes that you've already passed:

... likely to require examination, adjustment, servicing, or maintenance while energized ...

It's just my opinion on this but ...

the handbook repeatedly states an example for examination to be using a voltmeter. And while energized usually refers to being in a state where that energy can be a hazard. Service I find questionable since I'm supposed to test my GFCI receptacles every month.

I personally don't see 110.26(A) applying to the pictured box until the cover is removed. The door doesn't seem relevant to me.
