Someone recently asked "How expensive can blank filler pieces be?"

In this panel, the white area is all one piece of very sharp-edge aluminum metal siding, cut to fit and mounted to the panel cover with screws.

Two Words: UNBELIVEABLE STUPIDITY

What, no copper siding laying around?

Doesn't the piece of sheet metal do a better job of closing the opening than the filler plates on the other side of the panel do?

(Sharp edges are no good when someone's fumbling around in the dark).

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.

Yes, Mike. If you look at the face of the cover, near the edge of the indented portion, you can see the screw heads. These were actually screw / nut fasteners, and not the self-drilling type.

Those little pieces of injection molded plastic are NOT a bargain at $1.30 each
There's about $30.00 worth (cost) missing out of this load center.

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!

Scott, darn your sharp eyes!

I actually have two pics of the inside of this panel, which is extremely well marked as to the high leg.

This industrial park does, in fact, have a row of units with a "high leg;" that is, 208v to ground, rather than 120. That row also has the high leg at position "C". BUT....

As well marked as the panel is, the markings were not changed when the PoCo upgraded to true three-phase service. I did check, and every leg is 120v to ground .. no high leg after all!
