CB1 protects RC1 and the genera-
tor winding from overload. If CB1

CB2 protects GFCI1 from overload.
If CB2 opens, GFCI1 does not
work. Press button to reset breaker.
. If a circuit breaker continues to
open, contact Factory Autho-
rized Service Agent.

by weld output.
Maximum output is 2.4 kVA/kW
from GFCI1 and 4 kVA/kW from
RC1. Maximum output from all re-
ceptacles is 4 kVA/kW.
EXAMPLE: If 13 A is drawn from
RC1, only 7 A is available at GFCI1:
(240 V x 13 A) + (120 V x 7 A) =
4.0 kVA/kW
