GROUND FAULT CIRCUIT INTERRUPTER RECEPTACLE
All models have a 120-volt ground fault circuit interrupter (GFCI) receptacle. The
GFCI receptacle is on the control panel or top cover of alternator (model
MGH3000 only). The GFCI protects you against hazardous electrical shock
caused when your body becomes a path through which electricity travels to reach
ground. This could happen when you touch an appliance or cord that is ‘live’
through faulty mechanism, damp or worn insulation, etc.
When protected by the GFCI, you may still feel a shock, but the GFCI should cut
it off quickly. A person in normal health should not receive serious injury.
Note:
Infants and very small children may still be affected.
Test Procedure
Check the GFCI receptacle every month. This insures it is working right.
1. Push black TEST button. Red RESET button should pop out. This should trip
GFCI, resulting in no electrical power at receptacle. Verify this by plugging
test lamp with good bulb into receptacle. If lamp does not work, GFCI recep-
tacle is good.
WARNING
If RESET button does not pop out, do not use the GFCI
receptacle. Contact a qualified electrician for repairs.
2. If the GFCI receptacle tests okay, restore power by pushing the RESET button
back in. The test lamp should work at this time. IMPORTANT: You must
press the RESET button firmly and fully. It should lock into place. If the GFCI
does not lock into place, do not use receptacle. Contact a qualified electrician
for repairs.
