I hate to be nit-picky, but the GRC nipple could be argued to be a violation of 250.6(A) and it appears that 250.92(B) may be violated if the KO's have any eccentric or concentric rings left on the box where the nipple is connected (and assuming there is no bonding bushing in the meterbase that I wouldn't be able to see).

PVC will solve both problems in the future.

That's one that I learned raht-cheer on ECN!

(Thanks Bill)

Actually, I lied...

I LOVE to be nit-picky!!!



Not a violation, but, no 40 space MLO's?

What do you think about the 200A sub (w/main) being fed from a 100A breaker?

I suppose as long as the lugs on the Main Breaker and the Neutral and EGC Lugs are rated for the size of wire used, it still offers a convenient "bus disconnect" and the 22KAIC protection.

Plus, like here, a 200A 30 or 40 space MLO may be actually more expensive and require a special order!

Not a code violation, but my PoCo requirements would want the straps on the mast within 12" of the meterbase (minimum 30" spacing and within 12" of the weather head).

Why are there white wires connected to the circuit breakers without re-identification? The breaker in the upper left corner of the main panel looks like a Siemens not GE. Most of the cables in the main panel appear to enter through 1 KO and I have never seen a connector listed for more the 4 cables. The main lugs on 200 amp GE load centers are listed for min. #1 conductors and the wires feeding the sub panel look smaller but its hard to tell with this picture.

Wow, I missed all that at first...

I've got to go to bed...

(Note time of post)

Oh, to add... Just a hunch, but the service entrance neutral connected to the top lug of the meterbase and the service feeder neutral appears to have been stripped from a piece of SER (going by the white stripe). I would think that THWN or RHW-2 or the like would be required here.

Is that rigid nipple OK between the meter socket & panel? Should it be a Meyers hub?
The GEC connection is made at the meter socket. I believe our PoCo forbids that.
Also, although not a violation, see my post about excessive NM jacket in the panel.

Is there a connector on the egc at the meter or is it routed through 1/4 inch k.o?

LOL at txsparky.... You're a bad man!



Redsy, yep, that's what I was getting at with the GRC Nipple violating 250.6(A)for parallel current paths and perhaps 250.92(B)for a lack of bonding bushing.

I still can't believe I didn't see all those white conductors before!
