Generator

Honda EU3000iS Inverter Generator

The short answer

This generator makes up to 2,800 watts and can start motors that briefly need 3,000 watts. It runs on gasoline.

It supplies 120 volts only, so it cannot run 240-volt equipment such as a typical well pump. Of the 15 household loads we track, it can handle 15.

It must run outside. The exhaust contains carbon monoxide, which you cannot smell and which kills.

Outdoor use only

This generator burns fuel and produces carbon monoxide. Run it outdoors only, well away from doors, windows and vents, with the exhaust pointed away from the building. Fit working CO alarms indoors. CO-MINDER™ continuously monitors carbon monoxide (CO) levels. It automatically shuts down the generator before detected CO levels near the generator become dangerously high.

Runtime for a generator is a fuel question, not a capacity one — see the table above.

Fuel and runtime

Runtime is quoted at half load. Your actual runtime falls as load rises, and refuelling a hot generator is itself a burn and fire hazard — let it cool first.

Outlets

  • one 20A 125V duplex receptacle
  • one 30A 125V locking-plug receptacle

Outlet configuration decides what you can plug in directly. Powering house circuits instead of appliances requires a transfer switch or inlet installed by a licensed electrician.

Safety boundary

  • Outdoor only. Carbon monoxide from this unit is lethal and undetectable by smell.
  • Backfeeding is prohibited. Never run a cord from this generator into a wall outlet. It can kill line workers restoring your power.
  • Any connection to building wiring requires a licensed electrician and, in most places, a permit and inspection.
  • Store fuel safely and away from the running unit. Let the engine cool before refuelling.
