Sears 919.32721 owner manual Receptacles, Generator Capacity, Obtaining Electricity From Generator

RECEPTACLES

Your generator is equipped with duplex 120 volt receptacles and a twistlock 240 volt receptacle.

The unit is also equipped with a 20 amp circuit breaker for the 120 volt receptacles and a 20 amp circuit breaker for the 240 volt receptacle which is provided to protect the generator against electrical overload. If the circuit breaker trips, unplug electrical load from receptacle. Let circuit breaker cool down and then push circuit breaker button to reset.

The guide below is provided to assist you in determining the appliances and tools that can be ran with the wattage capacity of your generator.

GENERATOR CAPACITY

Exceeding the rated capacity of your generator can result in serious damage to your generator and connected electrical devices. You should observe the following to prevent overloading the unit:

•Starting and running wattage requirements must be calculated to match your generator wattage capacity.

Resistive load appliances such as light bulbs, TV's and microwaves, have the same starting and running wattage. The wattage used for calculating the capacity can usually be found on each of these appliances.

Some inductive appliances and tools will list on the motor name plate, the starting and running voltage and amperage requirements. Use the following formula to convert voltage and amperage to wattage:

(Volts X Amp = Watts)

Inductive load appliances and tools such as refrigerators, air compressors and washers require approximately 2 to 4 times the listed running wattage for starting the equip- ment. This initial load only lasts for a few seconds on start-up but is very important when figuring your total wattage to be used.

NOTE: Always start your largest electric motor first, and then plug in other items, one at a time.

OBTAINING ELECTRICITY FROM

GENERATOR

There are basically two ways to obtain electricity form a generator:

•Use of extension cords directly form the generator to the appliance, lights, tools, etc.

•Use of a double-throw transfer switch installed

directly to the main electrical supply outside of the house.

Extension Cord

When using an appliance or tool at a considerable distance from the generator, a 3-wire extension cord that has a

3-blade grounding plug and 3-slot receptacle that accepts the tool's plug should be used. A cord of adequate size must be used. A minimum of 12 gauge wire size with at least a 20 amp draw can be used. When amperage exceeds 20 amps a 10 gauge wire size should be used.
