7-1. Generator Power Receptacles And Circuit Breakers

 

 

 

 

Y If unit does not have GFCI re-

 

 

 

 

 

ceptacles,

use

GFCI-

 

 

 

 

 

protected extension cord.

 

 

 

 

. Generator power decreases as

weld current increases.

 

 

 

1 240 V 50 A AC Receptacle

 

 

 

 

 

 

 

 

 

RC1

 

 

 

 

 

 

RC1 supplies 60 Hz single-phase

 

 

 

 

power at weld/power speed. Maxi-

 

 

 

 

mum output is 9.5 kVA/kW.

 

 

 

 

 

2 120 V 20 A AC Duplex

 

 

 

 

 

 

Receptacle RC2

3 120 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.

Circuit Breaker CB1

 

 

 

 

 

CB1 protects receptacles RC1, RC2,

 

 

 

 

RC3, and 115 volt ac output to Re-

 

 

 

 

mote Receptacle RC4 from over-

 

 

 

 

load. If CB1 opens, the receptacles

 

 

 

 

do not work and 115 volt ac output to

 

 

 

 

Remote Receptacle RC4

stops.

 

 

 

 

Place switch in On position to reset

Circuit Breaker CB4

 

 

 

 

 

CB3 protects RC2 and CB4 protects

 

 

 

 

RC3 from overload. If a circuit break-

 

 

 

 

er opens, the receptacle does not

 

 

 

 

work. Press button to reset breaker.

 

 

 

 

. If circuit breaker continues to

open, contact Factory Authorized Service Agent.

Combined output of all receptacles limited to 10 kVA/kW rating of the generator.

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

2 x (120 V x 20 A) + (240 V x 20 A) = 9.6 kVA/kW
