Single-Phase Generator Power

1 120/240 V 50 A Receptacle RC5

RC5 is connected to the optional three−phase generator and supplies 60 Hz single-phase power at weld/ power speed. Maximum output from RC5 is 12 kVA/kW. Power available at RC5 is reduced when welding.

2 Circuit Breaker CB7

Circuit breaker CB7 protects single- phase receptacle RC5 and the load wires from overload. If CB7 opens, all generator output stops and the recep- tacle does not work.
