The first Generac transfer switch that you've sited is for an Essential Circuits system. This is an indoor transfer switch with a built-in sub-panel. It does not get located between the meter enclosure and the building service disconnect. It allows you to power X # of circuits that must be active during a power outage. The second is a Whole House transfer switch with load shedding. In this case it is service rated because it has a main breaker in it and does get located between the meter enclosure and the existing building service disconnect thereby making it the new building service disconnect. Grounds and neutrals should be terminated here accordingly.
The controversy here is with her interpretation of when neutrals and grounds have to be terminated at the transfer switch. The way I read her statement is that the only time this has to be done is when you have a separately derived system and are switching the neutral OR if the manufacturer states it must be so. I believe the vast majotity of us here in the Forum disagree with that.
If you look at this Kohler automatic transfer switch you'll notice that comes with no service disconnect. This is an outdoor unit that looks like it's designed to go between the meter enclosure and the building service. disconnect.http://www.electricgeneratorsdirect.com/manuals/RXT SPECS.pdf
I hope someone can explain where this might be used. BTW, the reason why my reply sounded like it did was because you cited several Code references and offered no explainations. I wasn't out to insult you or cause you any heartburn.
