Voltage L-L: 416/480V
Voltage L-N: 240/277V
Voltage CT – N: 120/139V
Parallel Wye (208/240V 3ø)
Voltage L-L: 208/240V
Voltage L-N: 120/139V
NOTE:
208V is Standard Voltage
Series Delta (240V 3ø)

Voltage L1/L2-N: 120V
Voltage L3 – N: 208V
NOTE:
L3-N is a “High Leg”
208V instead of 120V!
Double-Delta (120/240V 1ø)
Voltage L-L: 240V
Voltage L-N: 120V
Preferred Single-Phase Connection.
Don’t Use Zig-Zag if Possible.
NOTE:
Derate generator by 1/3 rated
capacity when using this connection!
