I,m a journeyman in a large industrial facility and am encountering floor mtd rails mounted so close to 480 panels you can't comfortably open the access door. These have removable cross rails but wouldn't this violate "readily accessible"

Farmer, sounds like to me that you would but let's get real...

You need to ask yourself:

"Is raising hell about this worth losing my job over?"

Seriously...

(Double posting to avoid the "mad editor" syndrome that I have)

Let me add to this:

If it is an installation that you are in charge of, do it to code. If it is a pre-existing condition that you did not install, see-no-evil...

Your job depends on it.

are the cross rails readily removable?
