ground rod needed for cabin

[Stevenfyeager]

A customer's fishing cabin has a pole (we installed) with a 100 amp disconnect, with a ground rod. (the POCO only required one rod). This county has no permits or inspections, so I just did what the engineer said. This will feed a cabin 5 feet away from it. I am using #2 SER to the cabin. But I also need a second ground rod with the cabin panel, correct ? Thank you.

You feeding the cabin panel with a 4 wire service?

It's a sub panel, so I need to, correct ?

Yes in my opinion you're good.

Why is the POCO involved if it's a subpanel? Where is this subpanel being fed from?

The service panel is on a pole feeding a separate detached building? If so how do you plan to route SER cable? It is not permitted to be installed underground.

You should use URD and go underground. But since you're in Indiana, I could see some one using SER strung from pole to pole.

I’m sorry. Typo. No SER, I must have had a different job on the mind! 4 wire conductors in conduit. My main question is I need another ground rod coming from the cabin panel correct? Even though it’s only 5 feet away from the first ground rod.

Yes, It might be possible to share one but it needs to be as close to the new service as possible. You do know the NEC requires 2 grd rods at each building service with some exceptions of course. But Indiana has not got on that subject yet.

Parallel neutral current will be unavoidable, unless you drive two, unconnected rods.

As was mentioned, NEC requires two rods. If you have no inspections you could leave it as is. If you drive another rod, you don't need to tie it to the panel in the cabin. You already have one at the disconnect, you would just connect to that one. I would probably just leave it as is.

Thank you.
