Without knowing the amperage of the particular fridge, my guess is that
you'd be close but Ok. It is likely that other outlets are on that circuit
that you are not aware of though

I'm the OP and this discussion is proving to be very helpful. Thanks!
It looks like if I go with the 600 W transformer it will use a
substantial chunk of the capacity of that 15 amp circuit. The only
other non-trivial item on the circuit is a refrigerator in my garage.
Do y'all think the circuit can handle 600W transformer + fridge?

Thanks again.... Tom in PA
