power at weld/power speed. Maximum
output from RC2 or RC3 is 2.4 kVA/kW.
4
240 V 50 A AC Receptacle RC5
RC5 supplies 60 Hz single-phase power
at weld/power speed. Maximum output is
11 kVA/kW.
5 Supplementary Protector CB1

GFCI2 and GFCI3 supply 60 Hz single-
phase power at weld/power speed. Maxi-
mum output from GFCI-2 or GFCI-3 is 2.4
kVA/kW. Circuit protection is the same as
standard receptacles.
If a ground fault is detected, the GFCI Re-
set button pops out and the circuit opens
to disconnect the faulty equipment. Check

weld/power speed and press Test but-
ton to verify GFCI is working properly.
Combined output of all receptacles limited
to the rating of the generator.
Example: If 20 A is drawn from each 120
V duplex receptacle, only 26 A is available
at the 240V receptacle:
2 x (120 V x 20 A) + (240 V x 26 A) = 11.0
