Hopefully the photo is attached.
Does the installation comply with the NEC?
I think the main question is - Can the box be supported by the conduits?

Is that PVC supporting the box?

If so, 314.23(F) does not seem to allow this.

(F) Raceway-Supported Enclosures, with Devices, Luminaires,
or Lampholders. An enclosure that contains a
device(s), other than splicing devices, or supports a luminaire(
s), lampholder, or other equipment and is supported by
entering raceways shall not exceed 1650 cm3 (100 in.3) in
size. It shall have threaded entries or have hubs identified for
the purpose. It shall be supported by two or more conduits
threaded wrenchtight into the enclosure or hubs. Each conduit
shall be secured within 450 mm (18 in.) of the enclosure.

I agree if that is PVC supporting the box then it is a violation.

One fix is to drive uni strut behind the box & attach box to strut with a spring nut.

Other fix drive 1/2 or 3/4 rigid with the threads up & screw box on the rigid. Then use the

other knock out for PVC supply.

They also make a one hole strap that threads into the KO in the back of the box so you could just drive a piece of rigid behind the box too.

It would have to be schedule 80 PVC. My local supply house in NC does not carry schedule 80 in 3/4 PVC

Buck the schedule 80 is for protection but it has nothing to do with supporting the box. I usually drive a piece of unistrut in the ground or use a 4x4 post.

BTW, I think city carries schedule 80-- they used to anyway.

The weight supported by any single conduit does not exceed 9 kg (20 lb).

Does it make sense to change from rigid galvanized to PVC after the first bend underground?

Is there a minimum ht of the receptacle above ground?


(I'd look the second one up myself but it is 90 out and I want to take the cycle out for a frapacino)

Isn't exception 2(E) referencing a luminaire???? That is what exception 2 is about.

Yes, and I was trying to understand the reasoning behind why a single conduit can?t support a device box, but can support a luminaire under conditions. I believe I see the reasoning.
