Knowing the box is Square D, is there a way to tell what type of 2-pole 90a breaker I need for this particular type of box from the pic?

QO290

The metering is done with the ct that's visible between the pole top and the transformer. The rust colored box most likely has a generator connection inside it.

That still doesn’t change the fact that he can pull a branch feeder from the 200 amp main service panel he has

Finally talked to an AHJ gentleman. No meter or pole required for this project.

Strangely enough he suggested URD as opposed to MHF. He seemed un-assured about the MHF being direct burial. Also, he was very specific in stating that URD can be used within building structures as long as the cabling did not extend in length in great distances.

I'm sticking with MHF for the reasons stated in this post.

Typical inspector that doesn’t know his wire types

Gotta be honest here...a lot of your posts lately feel like you are just trying to argue. Maybe that's just my impression though.


I was looking at it as a fresh feed from the utility service. Nothing more than that. I've posted a couple other times in this thread that he can come from the panel at the pole without an issue. A mistake/misunderstanding in one post...not a big deal

Not arguing. I ask questions to understand why people suggested something when it contrasts what the OP has.

I agree that is a good option. However if he wanted more than a 100A feed to the shop I would bypass that 200A box and tie it in right after the pole top

wylie and Bert_, thanks for the input regarding pulling a branch feeder to juice the shop. Duely noted. It sounds like a great idea if I start tripping the shop breaker! And if that does happen I'll be in a world of hurt'n based on what the AHJ told me on the phone.

Thanks guys, your gold!

Very unlikely you are going to trip a 90A breaker for the shop unless you add multiple large loads and have several people working there at once. Even then it's going to be hard to do.

....... I was thinking about one of the things our AHJ said to me on the phone. He mentioned that if we are going to use a 90 degree elbow fitting for the PVC portion of this job that we would need to use an expansion fitting. If we go straight up with no elbow, an expansion fitting would not be necessary. We can just go straight up on this, right?

If you aren't using conduit for the horizontal portion of the run and just using direct burial cable then a bend at the bottom of the riser isn't usually used. The conduit just ends a bit above the trench bottom (to allow for a radius on the wire) and no expansion fitting is needed. If you are doing conduit on the horizontal portion (continuous conduit) then a bend is needed and an expansion fitting should be used.

Thanks Innovate1. Love it when a good plan comes together!

I realize this has been a lengthy post but curious to know - Can I assume the main breaker box located at the pole is the panel that would be bonded? ..... and not the box in the house or the one that will be installed in the shop outbuilding -

The first means of disconnect can be the only place bonded. Everything downstream has to be unbounded and supplied with a 4 wire feeder (assuming you want 120 and 240v circuits)
