I will be wiring a Generac 24kW Generator, connecting into a 200A Generac Automatic Transfer Switch. This Transfer Switch’s output is then powering a 200Amp service panel. The Generator’s max output is 100A (24kW @ 240V), and it also has a 100 Amp main line breaker on the Generator itself.
When wiring (3-wire) to the generator, can I to wire for 100A (e.g. 00 aluminum wire)? Or do I have to wire for 200A (e.g. 0000 aluminum wire)? There is a tremendous difference in price and effort. It will be about 80 ft from transfer switch to generator (about 2/3 inside and about 1/3 buried outside in pvc conduit)
The maximum that can actually travel down that wire is 100 amps of current (even though it’s connected to a 200A transfer switch & 200A panel). If 101 amps are called for, the 100A breaker on the generator will flip to prevent generator overload. So is 00 aluminum allowed in this situation?
