Product Description

10kW standby generator with the only pre-wired whip and transfer switch for indoor & outdoor placement from Briggs & Stratton supply your home with power during utility outages even if you are on vacation, at work, or sleeping in your bed. If power is interrupted, the standby generator and automatic transfer switch senses the outage. The generator starts and the automatic transfer switch moves your home onto generator power within just a few seconds to keep your home safe, secure, and comfortable with minimal interruption.

Placement & Safety

Briggs & Stratton designed the new 10kW generators with a front-facing exhaust and for full compliance with NFPA 37 (National Fire Protection Association regulations for placement of internal combustion engines) which allows more placement options than other generators in the same power class. An automatic, thermally-activated fuel shutoff valve and all steel cabinet make these standby generators safe for installations as close as 18 inches to the home. They fit well in small yards and where tight lot lines make placement difficult for other generators.


Briggs & Stratton uses a Vanguard 550 cc OHV commercial duty engine in its 10-kilowatt standby generators for long-lasting, reliable performance and durability. Improved easy access to the engine and alternator ease routine maintenance when it's time to add oil or change filters and spark plugs. The time-tested Vanguard engine ensures your generator will start when the power goes out and keep keep running until utility power is restored.

The engine operates on natural gas or liquefied petroleum (LP) gas. Briggs & Stratton standby generators are configured at the factory for natural gas with a fuel selector for propane.

Automatic Transfer Switch

Our Birggs & Stratton 10kW is designed to be a true 100-amp select circuit transfer switch with an air conditioning management option (ACCM) for up to TWO air conditioners (load dependent) and 30% more available circuits. Saves up to 30% installation time - no need to purchase, measure and cut wire, it's all included.  Pre-wired to the transfer switch circuit breakers to eliminate additional steps in installation.

Eliminate wasted time trying to make a transfer switch fit due to limited placement options.  The Briggs & Stratton pre wired transfer switch can easily be mounted on either side of the circuit breaker panel.  This cuts the need for you to figure out a solution when breaker panels are not in ideal locations, saving you time and frustration.

As one of the few transfer switches in the industry that offer Nema 3R ratings for indoor and outdoor placement, you can customize the location of the transfer switch.  The seal-tight conduit provides maximum protection against dirt, rain, sleet and snow (2' for circuit breaker panel connection and 25' for generator connection).  Able to alter the length of wiring to the generator and still be UL compliant.


The onboard controller monitors the engine and alternator output, and maintains the correct generator frequency and voltage for clean power comparable to the electric utility and suitable for computers and other electronic devices. The safety sensors include low frequency or voltage, low oil shutdown, engine temperature and speed, transfer switch status, and battery voltage.

Appearance and Noise

The 10kW standby generator from Briggs & Stratton isn't much louder than a five-ton central air conditioner.  It has the smallest footprint in its power class at just 35 inches high, 28 inches wide and 24.4 inches deep. The Gavanneal steel cabinet―the same steel used by the automotive industry―offers a chip and rust-resistant finish that performs even in a coastal climate and keeps the generator looking good for years to come.

Optional Accessories

Cold-weather kits tested to -20 Fahrenheit ensure the generator will operate even in cold weather. The kits include a temperature controlled battery warmer and two oil heaters to ensure cold weather starting even in harsh, winter conditions.

A basic wireless monitor eliminates trips outdoors to check on the generator. Mount it inside and know your generator is operating as it should without making a trip outside to check its operation.

Maintenance kits include oil, oil filters, air filters, and spark plugs. You won't have to hunt for parts when your standby generator needs maintenance, and you'll know you have the right supplies to complete the job. Keep spare maintenance kits on-hand to ensure you have the required supplies during a long-term power outage.

Briggs & Stratton 10kW standby generators come with 5-year parts, labor and travel warranty.

Each system includes an hour meter, battery charger and synthetic oil. 

Packaged with Briggs & Stratton 100 Amp Automatic Transfer Switch with 16 Circuit Load Center and Nema 3R Cabinet.
