Power Connections from Generator to Transfer Switch

Utility Circuit Connection

“240V Utility” leads must be routed in conduit. The “240V Utility” leads deliver power to the generator’s circuit board, optional battery warmer and optional oil warmer. This power also charges the battery. When power on these leads is lost, the generator will start.

Generator Power Connection

For 8kW Units: Using installer supplied minimum 300V, 90°, 10 AWG copper wire, or 300V, 90°, 8 AWG aluminum wire*, connect generator power output Line 1, Line 2, neutral and ground to the corresponding Line 1, Line 2, neutral and ground in the transfer switch.

*Use National Electric Code for correction factors and wire size calculations.

Using installer-supplied minimum 300V, 14 AWG wire, connect each control circuit terminal in the generator (Utility A and Utility B) to the fuse block in the automatic transfer switch.

For 10kW Units: Using installer supplied minimum 300V, 90°, 8 AWG copper wire, or 300V, 90°, 6 AWG aluminum wire*, connect generator power output Line 1, Line 2, neutral and ground to the corresponding Line 1, Line 2, neutral and ground in the transfer switch.

*Use National Electric Code for correction factors and wire size calculations.
