back feed through I-line panel
back feed through I-line panel
(OP)
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?

They may wish to lock out and tag out your equipment, in addition to whatever you intend to do.
At least give them the opportunity to do so.

One thing to be careful of in a back-feed operation is the settings of the trip unit on the circuit breaker. A lot of the new 'intelligent' trip units from Schneider now come with functions such as "Reverse Power Flow" hidden down in the menu.
If you have one of these smart style trip units, make sure you read through the manual and disable any functions that may cause an issue.
