Does anyone know any 320A Meter Pans that are specifically non residential?

I have only found residential models.

It is for an upgrade from a 200A service to a 400A at a Cell Tower Equipment Trailer.

The contract with the client specifies commercial/industrial type equipment only and I am trying to avoid any issues.

I personally would much rather install a CT cabinet, much easier to route conduit & shape 500kcm conductors in. But JCPL is fighting me on using a CT enclosure for a 400A Service.

Thanks for any help.

We use them, here's a link to a listing http://www.txuelectricdelivery.com/community/construct/guidelines/section500.pdf
the have several manufacturers in two different sizes. Look for book page 45.
