Calculating Total Wattage of Devices Used with the Generator
Before using the Generator, check that the products
you want to plug into the unit are below the rated and
maximum wattage ratings of the Generator. Use the
Wattage Calculation Table below, and the watts listed on
your products, to help calculate multiple wattage totals.
To use the table:
1. Add up the Running Watts for all items you
would like to use at any given time.
2. Make sure that this total is under the 7,250
running wattage of the Generator.
3. Find the single highest starting watts for
the selected items and add to the total.
4. Make sure that this total is under the 9,000
max. starting wattage of the Generator.
5. Plug in and turn on products from
largest wattage to smallest.

Example
Equipment
Electric Water Heater (2,000 + 0)
Television (400 + 0)
Lawn Mower (1,200 + 1,200)
Hand Drill (600 + 600)
Total Running Watts
(must be less than 7,250)
Largest Additional Start-up Watts
Total Startup Watts needed for all loads
(must be less than 9,000)
A generator that is rated more than the minimum
required max. starting watts will last much longer than
a generator that only supplies the exact watts needed.
To Calculate Wattage:
Volts and amps can be multiplied together
to get watts (volts x amps = watts).
To Calculate Additional Start-Up Watts
(If They Are Not Listed)
For equipment with a motor: Use the rated watts
amount as an estimate of additional Start-up Watts.
For most lights or heaters:
there are no additional start-up watts.
