Residential. I have a 320amp meterbase with double lugs. Currently, I only have 1ea. 200amp main breaker panel box connected to the meterbase. The panel box is located inside the house. Can I put a second 200amp panel box outside the house (lugged to the same meterbase)? If I did that, I would have one disconnect on the inside of the house, and one on the outside. When I looked that up several years ago, I came up with "no" as an answer. I wanted to see if my answer was wrong as usual.
grouped disconnect?

As far as I know if you have multiple disconnects they have to be groped adjacent to one another.

If you were to put the 2nd panel at another building/structure, such as a garage, barn, shed. etc, then you could run a set of SE conductors to the other panel from the 2nd set of lugs in the meter. You wouldn't have to have the disconnects grouped in this scenario as it's an exception for a dwelling. I don't have time at the present to give you the code articles. If no one else does by the time that I return, I will look them up and post them.

I love it when you talk dirty.
I believe it's covered by Exception #3 to 230.40.
I have seen a few POCOs who would not allow that install but the NEC does.

Seems to me that I've heard that about POCOs!
