Wattage Guide

Honda's Handy Wattage Estimate Guide


Not sure how much power you need? Follow this handy Honda Wattage Estimate Guide to help you choose what is best for you.

Starting power versus operating power? Electrical loads are mostly divided into two types of load: resistive and reactive. Resistive loads such as light bulbs, coffee maker, usually include a resistance to provide or generate heat, and use the same amount of power to start and operate the appliance or application.

Reactive loads such as furnace fans, A/C, refrigerators, usually include an electrical motor that needs additional power to start or starting power. Once started, these appliances or applications operate normally or operating power.

Maximum power refers to the maximum output a generator can supply. It usually is for no more than 30 minutes.

Generator Safety Tips


Your safety is very important to us, so below are a few tips concerning safety while operating a generator:

Carbon Dioxide:

  • Only run a generator OUTSIDE, far away from windows, doors, and vents
  • Never operate a generator inside a house, garage, basement, crawl space, or any enclosed or partially enclosed space.
  • Never operate a generator near open doors or windows.

Electrocution:

  • Using a generator in wet conditions such as in rain or snow, near a pool or sprinkler, or with wet hands could result in electrocution. Keep the generator dry.

Fire:

  • Let the engine cool before storing the generator indoors.
  • Keep flammable materials away from the generator when it is running.
  • Keep the generator at least three feet (one meter) away from buildings when the engine is running. The generator needs at least three feet of clearance on the top and all four sides for cooling.
  • Gasoline is extremely flammable and gasoline vapors can explode. Do not refuel while the engine is hot or running, and do not overfill the fuel tank. Refuel only outdoors in a well ventilated area. Never smoke near gasoline, and keep flames and sparks away. Store fuel in an approved container.
  • Be careful not to touch the muffler while it is hot.

 

*** Please follow the instructions in the owner’s manual and on the generator safety labels ***
