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!
