Default Code compliant?

320 amp meter feeding two 200 amp panels. Would it be a violation to have a properly installed 200 amp automatic transfer switch and generator connected to only one of the panels?
Have a home inspector saying it is a violation.

Ask the HI for a Code reference. That should shut 'im up.

Good read on the subject here:

http://www.inspectionnews.net/home_i...0a-panels.html

There would be no code violation just feeding one of the panels with back up power.

In so far having one ATS feed a panel single panel like in the thread is complaint. Guy has some other violations but this is ok.

Will the ATS become the service disconnect for one of the panels?

If so, will your service disconnects remain grouped?

The argument by the HI is that the structure will be supplied by two services during a delay of transfer upon restoration of utility power.

The structure will not be supplied by two services under any condition. Tell the HI to look at the definition of SERVICE in article 100 of the NEC.

The violation you actually have (at least the most glaring) is the fact that you are using a Service Rated ATS (which becomes a service disconnect) and now your service disconnects are not grouped.

In any case I think that thread would make a good discussion here.
