Never exceed the rated capacity of your generator. Se ri ous damage to the

generator or appliance could result from an overload.

Starting and running wattage requirements should always be calculated

when matching a generators wattage capacity to the appliance or tool.

There are two types of electrical appliances that can be powered by your

generator:

Items such as ra di os, light bulbs, television sets, and microwaves have

a "re sis tive load". Starting wattage and running wattage are the same.

B. Items such as re frig er a tors, air com pres sors, washer, dryer, and hand

tools that use an elec tri cal motor have an "inductive load". Inductive

load appliances and tools require ap prox i mate ly 2 to 4 times the list-

ed watt age for starting the equip ment. This ini tial load only lasts for a

few sec onds on start-up but is very im por tant when figuring your total

wattage to be used.

C. Al ways start your largest electric motor first, and then plug in other

items, one at a time.

NOTE: On 120-volt loads the maximum starting wattage should NOT exceed

one half of the rated gen er a tor wattage. Example: a 5000 rated wattage

generator = 2500 maximum starting wattage.

DETERMINING WATTAGE REQUIREMENTS

Before operating this generator list all of the appliances and/or tools that are going

to operate at the same time. (Then determine the starting wattage requirements

and the running wattage requirements by following example and/or refer to

household wattage calculator.)

First total the running wattage of all appliances and/or tools that will be

operated at the same time.

Example 1:

Lights

Television

Slow Cooker

Next the starting wattages of any appliances and/or tools that will start and

stop during operation.

Example 2:

Small Refrigerator

TOTAL

The running wattage of examples 1 & 2 totals 1150 watts. The starting

wattage of the small refrigerator is 2000 watts which is 1500 watts more

than the running watts. Take this difference of 1500 starting watts from the

refrigerator and add to the total running watts of 1150.

Example 3:

TOTAL

Generator must have a maximum capacity of at least 2650 watts.
