Standby Generator wiring to Transfer Switch

caseyc0815
13 years ago

My 20kw Generator is located approx 30ft from the Automatic Transfer Switch location. The genset has a double 100amp (each) breaker near the control panel. Internally, the power wires are connected to one side of each breaker. The wires going to the transfer switch get connected to the other side of each breaker. The internal wires look like they are #6AWG possibly #4 (can't make out any size printing on the wire) but its about the size of sparkplug wire and stranded. What size wires would be required to connect the other side of the breakers to my transfer switch 30 feet away?
