1 120 V 15 A AC Duplex Receptacle
RC1
2 120 V 15 A AC Duplex Receptacle
RC2
3 120/240 V 42 A AC Straight
Receptacle RC3
4 120/240 V 42 A AC Twistlock
Receptacle RC4 (Optional)
RC1 and RC2 supply 60 Hz single-phase
power at weld/power speed. Maximum out-
put from each duplex receptacle is 1.8
kVA/kW.
RC3 and RC4 supply 60 Hz single-phase
power at weld/power speed. Maximum out-
put from RC3 or RC4 is 10 kVA/kW.
Combined output of receptacles is limited to
10 kVA/kW output of generator. If maximum
output is exceeded, auxiliary equipment may
stop or not run properly.
5 Circuit Breakers CB1 And CB2
CB1 and CB2 protect RC1 and RC2 from
overload. If a circuit breaker opens, the
receptacle does not work.
6 Circuit Breakers CB3 And CB4
CB3 and CB4 protect all the receptacles
from overload. If CB3 opens, RC1, RC3 and
RC4 do not work. If CB4 opens, RC2, RC3
and RC4 do not work. 120 volts may still be
present at RC3 and RC4.
7 Ground Fault Circuit Interrupter GFCI1
GFCI1 provides ground fault protection for
the auxiliary power receptacles. If a ground
fault is detected, GFCI Reset button pops
out and the receptacles do not work. Check
for faulty tools plugged in receptacles. Press
button to reset.
. At least once a month, run engine at
weld/power speed and press test button
to verify GFCI is working properly.
8 Auxiliary Power While Welding Table
. Auxiliary power available at ac
receptacles decreases as weld
amperage increases.
