weld/power speed. Maximum output is 10.5
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 out-
put from RC2 or RC3 is 2.4 kVA/kW.
4 Supplementary Protector CB1
CB1 protects receptacles RC1, RC2, and
RC3 from overload. If CB1 opens, the recep-
tacles do not work. Place switch in On posi-
tion to reset.
5 Supplementary Protector CB2

weld/power speed and press Test button
to verify GFCI is working properly.
Combined output of all receptacles limited to
10.5 kVA/kW rating of the generator.
EXAMPLE: If 20 A is drawn from each 120
V duplex receptacle, only 23 A is available at
the 240V receptacle:
2 x (120 V x 20 A) + (240 V x 23 A) = 10.5
kVA/kW
