We are looking to back feed power, in case of loss of our generator, through a circuit breaker from a branch feed used to load bank test a generator. The breaker will be a Square D PGA36100SA rated to 1000 amps at 480 volts. All other power to the building will be down while repairs are made to a substation and this method has the automatic transfer switch downstream.
Is this ok or are there issues I need to be aware of?
