Introducing the new EF5500P Industrial Series generator with GFCI protected receptacles. This versatile dual 120/240 volt unit is ideal for primary power sources for industrial & commercial applications such as construction sites but can also be used for home, cottage or business emergency backup power too. The EF5500P sets new standards for performance and value.

Convenient and Easy To Use: EF5500P comes standard with wheels, fold-down/locking handle and convenient lift hook.

GFCI Equipped: The EF5500P features GFCI receptacles which monitors the amount of current flowing from hot to neutral. If an imbalance is sensed, the GFCI automatically trips the circuit and cuts the flow of electricity to help prevent shocks.

  • Powered by Yamaha's MZ360; 357cc, air-cooled (fan assist), OHV, 2-valve, 4-stroke, single cylinder engine with transistor controlled (TC) ignition.
  • Manual recoil starting with auto decompression system for a light, easy recoil starter pull.
  • Lightweight piston and offset cylinder design reduce frictional losses for improved fuel economy.
  • Manual choke
  • Maintenance-free brushless alternator offers superior reliability and reduced maintenance.
  • Dual 120 & 240 volt output makes the EF5500P very versatile
  • Damper Winding alternator reduces wave form distortion for "cleaner" power (power is almost as clean as an inverter)
  • Ground Fault Circuit Interruption (GFCI) senses a leak to ground and automatically shuts down power to reduce risk of electric shock.
  • Rated AC output for continuous use is 4,500 watts / 36 amps @ 120 volts & 4,500 watts / 18.7 amps @ 240 volts
  • Economy Control System (when turned on) lowers the engine rpm when there is no load to conserve fuel and reduce noise and engine wear.
  • Yamaha's Oil Watch Warning System automatically shuts off the engine when oil level is low and will not re-start until oil is added, preventing costly engine damage and enhancing long-term durability.
  • Multi-function digital volt and hour meter
  • Electrical "noise" suppressor reduces electrical interference with TVs and radios.
  • Easy access, washable foam air filter reduces maintenance costs
  • Easy access oil drain plug
  • Cleanable spark arrestor stops sparks exiting from the exhaust
  • On-off fuel petcock lets you shut off the gas to run the carb dry for storage, helping to prevent stale fuel problems, which are becoming more common with ethanol based fuels.
  • Large fuel fill hole for easy filling. Fuel gauge is standard
  • Rubber vibration isolation mounts reduce vibration for smoother operation and reduced noise.
  • Rugged perimeter steel frame protects the generator, engine and battery from damage.
  • Folding handle and lift hook for improved portability
  • Never flat, non-pneumatic tires mounted to rugged steel axles.
  • CSA approved (Canadian Standards Association)
  • Meets or exceeds EPA & CARB Tier 3 emission standards
  • 3-year warranty for "residential / home" use or "commercial use."
