Yes, but you need the fourth wire. This sub-feed needs to have a dedicated ground wire.

In KY (unless something has changed in the last couple of years), most places will pass #4 copper or #2 aluminum for a 100A service. A few places used to insist on #3 copper, IIRC. I have no idea what "3/2" means, every KY electrician or inspector I know would say "use number 2 aluminum" or "use number 4 copper" when talking about this.

It sounds as if you started with "2-2-2-4 URD", which is intended for underground use. That could be part of the reason the inspector turned you down.

You should be aware that KY makes it very difficult for "another inspector" to pass an installation that has already been turned down by the a different previous inspector. So you will probably end up putting in 2/0 Al to make this pass anyway.

"petey racer"-I think he is putting in a seperate overhead service, not a subpanel. I took "...through the box, meterbase, and up through the weatherhead.." to indicate that anyway.

Uh...duh. I guess I missed that very obvious part.
Now where's that little red faced icon.......

Im in Tenn. I have 200 amp. Service comming to a pole that is on my property. I want to put the wire underground and bring it to the house's 200amp panel. Then go to garage with a wire to carry 100 amps. Garage is anout thirty five away. I want that wire for the 100 amp service buried also. Can some one give mr the proper proper wire size and regs. If you know them.

I'd suggest starting your own thread instead of piggy backing on this old one that is loosely related (The OP is talking about overhead wiring).

And you didn't state how far the pole is from your house panel.

Are you attempting to do this yourself? I imagine it needs to be inspected. If so, you could ask the inspector's office for the regulations.
