Zog, I was serious. I wouldn't have anything in the cell. If I had a breaker out for maintenance, the DS units that I have worked on, get their red arc chutes removed. Then we have one gap to check with the breaker open and one gap when closed. I also remember having to loosen 4 bolts because the contacts were rotated slightly on some breakers. We would then have to go through the Digi-trip settings with the Amptector. This was an activity that my group got stuck doing on regular time, 3 Saturdays a year, per contract. I'm certainly no expert from doing it 3 times a year, but I thought you couldn't lift the flap to get to the bolt on a closed breaker. I also thought that, on at least some cubicles, a shutter comes down as you rack out the breaker. Am I wrong there? I couldn't tell whose AC SWGR it was from the viewing angle but it looked like it could have been the type that I work with.
If you thought my first guess was silly, how about my second guess? They took out the main breaker and were trying to rack in a spare while they worked on the main. Guesses are guesses. No harm, no foul for a bad one.
