GENERATOR

GROUNDING

WARNING: You must prop- erly earth-ground generator be- fore starting. This will help guard against deadly electric shock. Only use grounded plugs with generator. Only use grounded ex- tension cords. Only use three- wire or double-insulated power tools.

Grounding generator helps prevent electric shock from a ground fault condition. Locate ground lug on end of generator housing (see Figure 13). Attach a #10 stranded-copper ground wire to ground lug. Drive grounding point into ground. Grounding point can be a stake, grounding rod, or pipe. Grounding point should be copper or brass. Attach ground wire to grounding point. You must supply the ground wire and grounding point. These do not come with generator. Follow the National Electrical Code and all state and local codes. Consult your power com- pany or a licensed electrician.

WARNING: For a grounding point, do not use metal pipe be- ing used to carry combustible materials or gases.

STANDBY INSTALLATION TO HOME OR BUILDING

WARNING: Have standby in- stallation performed by a skilled, licensed electrician. Do not let anyone else wire into a utility circuit. Personal injury, equip- ment damage, or damage to home could occur.

IMPORTANT: This generator will not power your entire home. Most home utility electric service is more than 60 amps. This will exceed generator output. Only power needed items during a power outage. Make sure total wattage of electrical load does not exceed rated wattage of generator.

You may need to use this generator as a standby power source. During a power out- age, the generator will power selected items in a building. Have generator and additional wiring installed by a skilled, licensed elec- trician. This is not a do-it-yourself job. Fol- low all local codes.

WARNING: The electrician must install a double-throw trans- fer switch. This isolates existing electrical circuits from the utility power line. If not isolated, gen- erator output will back-feed into utility power line. This may elec- trocute a power company line repair person.
