I was going to ask that question about the gen unit too....are the windings big enough to allow 70% overcurrent for 3 sec. without voltage sag and popping breakers
I wrote to Bill directly, but will post to the group.
"Momentary" power is specified with some generator units.
Kohler's diesel 10 kW gen set supplied 300% rated current for up to 10 seconds.
Generac did not give a spec.
So.... your mileage varies!
