			CB1 protects RC1/GFCI1 and CB2
			protects RC2/GFCI2 from over-
			load. If CB1 or CB2 opens, the re-
			ceptacle does not work. Press but-
			ton to reset circuit breaker.
			. If a circuit breaker continues to
				open,	contact	a Factory
				Authorized Service Agent.
			If a ground fault is detected, the
			GFCI Reset button pops out and
			the circuit opens to disconnect the
			faulty equipment. Check for dam-
			aged tools, cords, plugs, etc. con-
			nected to the receptacle. Press but-
			ton to reset receptacle and resume
			operation.
			. At least once a month, run en-
				gine at weld/power speed and
				press Test button to verify
				GFCI is working properly.
			Maximum output from each duplex
			receptacle is 1.8 kVA/kW, and 3
			kVA/kW		from all	receptacles.
			Auxiliary power is not affected by
			weld output.

EXAMPLE: If 15 A is drawn from

RC1, only 10 A is available at RC2:

(120 V x 15 A) + (120 V x 10 A) = 3.0 kVA/kW
