Briggs & Stratton 30471 is a 8,000/10000 Watt gas powered portable generator with Wheel Kit and electric start. It is not CARB Compliant and is intended for major power supply usage.

Briggs and Stratton have been in the business of manufacturing small engines and power equipment for over 100 years. They are well known for their Lawn tractors and other power equipment. Their range of generators include both portable as well as permanently installed.

The Briggs and Stratton 30471 generator is one of the portable generators that they manufacture and it can give out an out put of 8,000 watts continuously while being able to surge up to 10,000 watts.

With this kind of an output, this is a generator that can be used as a backup when you have power outages at your home or you could use it at your job site where you need to run your many power tools or even on your farm to run your electrical equipment.

This unit can be up and running in under 30 minutes and even as little as 15 minutes from the time you receive it.

Power Output and Generation

This Briggs and Stratton 30471 generator has a good supply of power at 8,000 watts continuous while being able to surge up to 10,000 watts.

It has a Briggs and Stratton 420 cc OHV engine with 21.0 ft-lbs of gross torque which runs at 3600 rpm. It comes with low oil alert and will shut down on low oil pressure. This is an electric start model and does come with a battery and has a recoil rope alternate.

The engine oil recommendation is for 36 oz (1L) of a synthetic 5W30 to cover all temperature ranges. Typically B&S provides the first oil fill. Additional options are given the owners manual if typical 10W-30 or other designations are used. Pay attention to this as oil consumption can increase. Also do not use special additives. Check the owners manual for best practices.

Electrical Output Receptacles

This unit has a very straight forward outlet panel with covered receptacles to protect against weather and debris.

This unit will supply AC Voltage at both 120 and 240 Volts,

  • at 240 Volts it has 33.3 Amps = 7992W
  • at 120 Volts it can supply 66.6 Amps =7992W
  • The unit has 2 duplex sets for four 3 prong NEMA 5 outlets with a max of 20 amps per set of outlets. In the wiring diagram the two bottom and two top are on the same circuit respectively. Therefore you could pull full 40 amps through one duplex set..
  • It has one L14-30 amp receptacle for 120V or 240V use.

This gives the ability to use all sets of outlets in combination up to the continuous rated 7992W and not overloading any one outlet. Example for a 120V say you use 27 amps from the L14 outlet you still have the ability to pull a combined 39.6 amps to pull through the duplex sets.

Fuel Type and Noise Levels:

The Briggs and Stratton 30471 generator uses unleaded gasoline as fuel. It has a large fuel tank which can hold up to 7 gallons of gas and the tank does have a fuel gauge. This generator is capable of running for 8 to 9 hours at 50% load capacity on one tank of gas. This is reasonable fuel efficiency, One user indicated he was burning about a gallon an hour even near full load.

Both the 10% ethanol or 15% MTBE are acceptable gasoline mixtures. 87 octane or 85 at high altitude are minimum levels.

The dealer can also provide high altitude adjustment kit to keep performance up. (Note that using the high altitude kit is only recommended for use above 2500 ft. Below that the engine will run to lean and potentially damage the unit.


There is no published sound level information on this unit. And with many Briggs and Stratton engines they are no especially quiet. One user commented that they thought the generator was as loud as a lawn tractor. Others indicated it’s not real loud.
