S-166 360-A

1240 V 30 A AC Receptacle RC1

RC1 supplies 60 Hz single-phase power at weld/power speed. Maxi- mum output is 7.2 kVA/kW.

2120 V 20 A AC Duplex Receptacle RC2

3120 V 20 A AC Duplex Receptacle RC3

RC2 and RC3 supply 60 Hz single- phase power at weld/power speed. Maximum output from RC2 or RC3 is 2.4 kVA/kW.

4Circuit Breakers CB1 and CB2

CB1 and CB2 protect RC1 from overload. If CB1 or CB2 opens, RC1 does not work. 120 volts may still be present at RC1.

5Circuit Breaker CB3

6Circuit Breaker CB4

CB3 protects RC2 and CB4 pro- tects RC3 from overload. If a circuit breaker opens, the receptacle does not work.

.Press button to reset circuit breaker. If breaker continues to

open, contact Factory Authorized Service Agent.

Combined output of all receptacles limited to 8.5 kVA/kW rating of the generator.

EXAMPLE: If 20 A is drawn from each 120 V duplex receptacle, only 13 A is available at the 240V receptacle:

2 x (120 V x 20 A) + (240 V x 15 A) = 8.4 kVA/kW
