The guy that wired this panel must have had shares in a wire-nut factory.

Is there anything supporting this big panel? What kind of strap is that holding the main breaker down...?

That's quite a bird's nest...

Looks like he took a 30 circuit MLO panel and backfed a 100 amp breaker for a main. Since there are no main lugs present, I am guessing that's a GE panel. They used to make them with a pair of main lugs that would occupy the footprint of two full pole spaces. My guess would be that he pulled out the lug module and replaced it with a breaker (hey, at least there's a main)!

I sure hope that strap holding the main down isn't made of metal because it sure looks like it's crossing directly over the bus bar.

I also like how he brought the armored GEC all the way into the neutral bar instead of stripping the armor. Maybe he just didn't know how to strip it.

I am not quite sure that I understand what the sub panel is even there for. It seems that the main panel still has plenty of spaces, although getting wiring to them might be a bit of a challenge.

Now, what about what appears to be a 14/2 NM exiting the left side of the big panel? It looks to either be cut off or embedded in the masonry wall.

"Shares in the wire nut factory"....Now that's funny! \:D

Ed,
I was looking at that last night and was wondering exactly what that wire was.
It does look a little strange to a person that very rarely sees that type of cable.
One other thing, how thick are the bus-bars used in these panels?

I think it goes behind the panel and is one of the two cables going into the receptacle on the right side.

Or else it is the cable coming up behind the backer board for the little sub panel.

Is that little panel a genny transfer panel? That might explain all of those red wires and wirenuts.
