Is the piece of sheet metal secured to the inside of the cover (well secured, I hope)? Those individual metal filler plates always bother me with the way they move around so easily. I'm afraid one is going to fall inside the panel, with possibly disastrous results.
Question(s) about this Panelboard - more as to the System feeding it...
I see something written at the top of the open door (on the back, above the specs sheet / circuit directory), which looks like:
"C Ø High Line"
Is this Panelboard on a 240/120V, 3Ø 4 Wire Delta System?
If so, position "C" is not the "NEC Preferred" location for the "Stinger Phase" - and from the looks of the 1 Pole Breaker(s) in position "C", the connected loads may experience a sudden loss of smoke, if they are rated for 120 VAC maximum.
Just wanted to toss this baloney out for purposes of chewing on it!
