20kW Standby Generator With 200 Amp Automatic Transfer Switch By Briggs and Stratton
A standby generator from Briggs & Stratton provides your home with backup electrical power. The 40346 is a 20-kilowatt, air-cooled generator packaged with a 200-amp automatic transfer switch. Connected to your home's existing electrical system and gaseous fuel supply lines, the fully automatic generator system starts and runs automatically within seconds of a power outage, providing electrical power to keep families and homes safe.
Adherence to National Fire Protection Association safety rules and National Electrical Codes allow placement as close as 18 inches to a home, offering maximum installation flexibility, especially where lot lines are tight and yards are small. These standby generators carry a four-year, limited parts and labor warranty.
Briggs & Stratton powers the 40346 with its own popular and reliable Vanguard 993 cc V-Twin overhead valve engine. The electronic engine governor incorporated into the generator design keeps the Vanguard operating at a constant 3600 RPM, even under heavy and changing loads, to keep the AC signal constant at 60 hertz. The aircooled engine has a fullypressured lubrication system and oil cooler, with a lowoil pressure sensor that allows engine shut down to prevent damage.
The 20kW standby unit is factory configured to run on natural gas, but converts easily to liquid petroleum gas (propane) during installation by simply turning a selector screw with an Allen wrench. Operating on LP gas provides up to 20 kW of power. At half-load, the engine consumes about 2.3 gallons of LP fuel per hour. Natural gas supplies up to 18 kW of power, and consumption runs about 83 cubic feet per hour at half load. Fuel consumption varies along with the electrical load and is affected by altitude and ambient temperature.
Standby generators are permanently installed appliances that operate automatically without intervention. A power outage is sensed immediately and after a short delay to prevent unnecessary starts during momentary outages, the engine is started and brought up to speed. The automatic transfer switch disconnects the home from the utility supply lines and connects it to the generator, effectively isolating the home from the electric utility.
The generator's controller continuously regulates the voltage and frequency to provide power that meets or exceeds electric-utility standards and is suitable for sensitive electronics in addition to lighting and appliance loads, including air conditioners.
The included 200-amp automatic transfer switch is a service entrance rated switch that includes the service disconnect. It installs indoors or outdoors and is typically placed between the electric utility meter and the main service panel. In this configuration, the switch controls the source of power to the main circuit breaker panel by selecting between utility power or generator power, which eliminates the need for additional subpanels and allows the generator to supply power throughout the home.
The air conditioning control module, or ACCM, allows the operation of two air conditioners. The ACCM "imprints" the starting current requirements of the air conditioners to prevent generator overload conditions and ensure the units only start when there is enough power available.
The addition of a load control center adds a managed power option which allows the generator to supply power to all your home's high-voltage, high current appliances including dryers, hot water heaters, and well pumps.
Maintenance kits include everything necessary to keep your generator running and supplying power, even through extended outages with oil and air filters, filler funnel, and spark plugs. Cold weather kits add two oil warmers and a battery warmer for easier and more reliable starts in cold weather down to -25 Fahrenheit.
Add a wireless monitor and keep track of your generator from indoors and eliminate trips outside during inclement weather.
The exterior cabinet is made from rustresistant Galvanneal steel and painted in a process similar to that used by the automotive industry for years of corrosion- free use. It rests on a prepared gravel bed or concrete pad, is 47 inches wide and 29 inches deep. At just 69db, the generator produces noise similar to a central air conditioning unit.

I got it installed before the hurricane Sandy and it worked tirelessly for 10 days! Easy to service. Norwall delivered it on time.

Had this installed in a new house I had built. Approx sq. ft. is 2700 with a 5 ton ac unit. 2 weeks after moving in we lost power and about 5 - 8 seconds later we had power from the generator. worked as advertised. As far as I'm concerned, it paid for itself already. Just having it on stand-by is great relief. I'd recommend this to anyone.

Exactly what I expected, installation was straight forward and look forward to having plenty of power during next storm which may cause balckout in my area.

This generator was installed in a home approximately 4K sf. Burned a little bit of oil.
