The GFI shuts off power to the receptaclewhen a ground fault occurs to a piece of equipment attached to thegenerator.The GFI should be tested for proper operation every time the generatoris used.To test the GFI:3.9.1 Disconnect all equipment from the generator.3.9.2 Start the generator.3.9.3 Push the TEST button (g) on the receptacle in. Pushing the TESTbutton in shuts off power to the receptacle and causes the RESETbutton (h) to pop out. If the RESET button does not pop out, the GFI isnot working. Do not operate the generator until the problem can becorrected.3.9.4 Push the RESET button in to restore power to the receptacle.If the RESET button pops out during operation, stop the generator andcheck the equipment attached to the generator for defects.3.10 Main Circuit BreakerSee Graphic: wc_gr003958The generator is protected by a two-pole, 15-Amp per pole, maincircuit breaker (d) located on the control panel.The main circuit breaker protects the generator from severe overloadsor short circuits. If the main circuit breaker opens, turn the engine offimmediately and determine the cause before restarting. Check theappliances and tools attached to the generator for defects and makesure their power requirements do not exceed the power rating of thegenerator or the current limit of the receptacles.
