James Godward said:Scott,
Generally the maker of the transfer switch will recommend against hot switching. The contactor contacts are not usually rated for that.
I would recommend that you don't do it unless you have a very good reason to do so. The extra minute or so should not make a big difference as the ACs etc. will lock out the restart for a couple of minutes anyway.
