120 V 15 A AC Receptacles
GFCI-2 And GFCI-3
GFCI-2 and GFCI-3 supply 60 Hz
single-phase
power at
weld/power
speed.
Maximum
output from each
receptacle is 2.4 kVA/kW (CSA:
1.8 kVA/kW).
If
a ground fault is detected,
Reset
button pops out and the circuit
opens to disconnect the faulty
equipment. Check for faulty tools,
cords,
etc. connected
to the recep

240 V 50 A AC Receptacle
RC1
RC1 supplies 60 Hz single-phase
power
at weld/power speed. Maxi
-
mum
output is 8 kV
A/kW.
3 Circuit Breakers CB1 And
CB2
CB1 and CB2 protect RC1 from
overload. If CB1 or CB2 opens,
RC1
and one of the 120 volt
recep
-
tacles does not work. 120 volts
may
still be present at RC1.
4 Circuit Breakers CB3 And
CB4
CB3 and CB4 protect GFCI-2 and
GFCI-3 from overload. If CB3 or
CB4 opens, the receptacle does
not work.
.
If
a circuit breaker continues to
open, contact a Factory Au-
thorized
Service Agent.
Total output of receptacles limited
to 8 kVA/kW. Example: If 20 A is
drawn from GFCI-2 and GFCI-3,
only
13 A is available at RC1:
