Gotta love the "ample" wire bending space in these panels. [Linked Image]

How did this junk ever get listed?

(Panel maker's name omitted to protect the guilty.)


Stupid should be painful.

Are those scorch marks I see on the bottom right-hand corner?

I'd love to know the brand of the panel, that way we know to avoid buying it!

How did this stuff ever get listed? Look at Zinsco and then ask the same question.

looks like the cement slab below sunk causing the fittings to pull out of the enclosure , common on long island usually 2-3 years after the pour..

Looks like a GE All-In-One. Atleast thats what those slim "mini's" lead me to believe.
But the bottom 2 pole is a Cutler Hammer.

So, how much wire bending space is required? In the '99 NEC, it's determined by Table 373-6(a)

Only 1-1/2" is required for the size of conductors here if they're #8 or #6, 2" if a #4 or#3. This provides that and more.
That's how it gets listed.
(BTW, these surface enclosures are basically the same design as the semi-flush version, made to fit in the space of a normal 16"OC stud bay)


As for the twin C/B's, these GE combination services are listed for their use, and I've not personally ever had to replace one that's burned up like a Zinsco.

The problem here was not the manufacturer,but the installer that slapped in the 1" PVC without a locknut (it would have pulled the concentric KO out if there was one), and wasn't careful about how he routed his wire to the C/B that really doesn't belong in this panel.(Besides being not listed for the purpose) The GE's have a little cross tab on the bus, and I don't think a CH has the slot to accept it. They won't stab on the bus all the way, so some guys just break off the cross-tabs, throw them in and use the deadfront to hold them in place.

Everything was probably fine until this Turkeylips came along [Linked Image]
Maybe a pool/spa installer that "does it all"?

turkeylips ??? Thats a new one for me. It is fitting though as that Cutler-Hammer 2 pole does not belong there. Also expansion fittings would have worked nicely in this installation. We use them in the northeast due to frost heaving the ground.
