An electrical panel mounting on a door surface

[xenuem]

I am wondering whether there exists a regulation within the NEC that explicitly prohibits the mounting of any electrical panel onto the surface of a door. The door in question is not associated with a building but rather forms part of a large container housing electrical equipment. The panel in question is responsible for controlling the devices contained within the container. The container is not intended for human occupancy and the panel is located on the inner side of the door so that it can be secured from outdoor environmental conditions.

Does the door open with panel mounted on the door?
Is there electrical clearance per 110.26?
A sketch would help.

Is this a panel board, with feeders and branch circuits, or an industrial control panel?
Electrical components, like pushbuttons and lights, are mounted on hinged enclosure doors all the time.

This is a brief sketch of it. I assume if the door is open, the clearance requirements can be met.

It is a control panel with feeder cables and control cables. I have seen small devices on doors but have never seen this type of panel on doors.

This only real issue is the conductors crossing the hinge. I have not seen many NEC compliant raceways with that flexibility.

Could the panel be moved to what appears to be the end wall of the container? No need for flexible conduit!

I wish I could, but the container is full of equipment, I just didn't show them on the sketch.

Thanks for the drawing on your post
Or turn the panel around, mount on strut, open the container door to access panel

Thanks for your input. That could be an alternative way to have a panel inside the congested container.

Raceways crossing the hinge is challenging. Some raceways like LTMC used where flexibility is required, but not like you propose.

If you don’t need that door to access inside, then having the panel facing out behind a door would always allow access!
