2.2CORD SETS AND CONNECTION PLUGS

2.2.1 AC, 20 AMP, DUPLEX RECEPTACLE

This is a 120 Volt outlet protected against overload by a 20 Amp push-to-reset circuit breaker. Use each socket to power 120 Volt AC, single phase, 60 Hz electrical loads requiring up to a combined 2400 watts (2.4 kW) or 20 Amps of current. Use only high quality, well- insulated, 3-wire grounded cord sets rated for 125 Volts at 20 Amps (or greater).

Keep extension cords as short as possible, preferably less than 15 feet long, to prevent voltage drop and possible overheating of wires.

2.2.2 120V AC, 20 AMP, GFCI RECEPTACLE

This unit is equipped with a ground fault circuit interrupter (GFCI). This device meets applicable federal, state and local codes.

Figure 8 - 120 VAC, 20 Amp GFCI Receptacle

Testing the GFCI: Test the GFCI outlet every month as follows:

•Plug a test lamp into the receptacle.

•Start the generator, the test lamp should be on.

•Press the “Test” button located on the front of the receptacle to trip the device.

•This should stop the flow of electricity making the lamp shut off. The yellow trip indicator should now be on.

•To restore the flow of electricity, press the “Reset” button on the front of the receptacle. If the GFCI does not perform in this manner, do not use the receptacle. Contact a local service dealer.

•This outlet is protected against overload by a 20A push-to- reset circuit breaker. Use the outlet to power 120V AC, single- phase, 60 Hz, electrical loads requiring up to a combined 2400 watts (2.4 kW) or 20 amps of current.

A GFCI receptacle is different from conventional receptacles. In the event of a ground fault, a GFCI will trip and quickly stop the flow of electricity to prevent serious injury.

Definition: Instead of following its normal safe path, electricity passes through a persons body to reach the ground. For example, a defective appliance can cause a ground fault.

A GFCI receptacle does NOT protect against circuit overloads, short circuits, or shocks. For example, electric shock can still occur if a person touches charged electrical wires while standing on a non-conducting surface, such as a wood floor.

2.2.3 120V AC, 30 AMP RECEPTACLE

Use a NEMA L5-30 plug with this receptacle. Connect a 3-wire cord set rated for 125 Volts AC at 30 Amps (or greater) to the plug.
