Automatic Whole-Home Backup Power
The Briggs & Stratton 040795 is designed to eliminate many of the inconveniences associated with manually operating a portable generator during an outage.
When utility power is interrupted, the 200 Amp automatic transfer switch detects the outage and initiates the standby-generator sequence.
Once generator power is available, the transfer switch automatically transitions the home's electrical system from utility power to generator power.
When normal utility service returns, the transfer switch moves the electrical system back to utility power and the generator completes its shutdown sequence.
Because this process is automatic, the standby system can respond whether you're home, sleeping, traveling, or away from the property.
22kW of Residential Standby Power
With 22kW of standby capacity, the PowerProtect 040795 is designed for homes with more substantial backup-power requirements.
Depending on equipment specifications and total electrical demand, a properly configured 22kW standby system may support loads such as:
- Central air-conditioning systems
- Heating equipment
- Refrigerators and freezers
- Well and sump pumps
- Lighting
- Internet and networking equipment
- Security systems
- Garage-door equipment
- Kitchen appliances
- TVs and household electronics
- Selected high-demand appliances
- Other essential household circuits
Generator sizing should always consider both running watts and starting requirements.
Air conditioners, pumps, compressors, and other motor-driven equipment can temporarily require considerably more power during startup than during normal operation.
200 Amp Service Entrance Transfer Switch Included
This package includes a 200 Amp service-entrance-rated automatic transfer switch, making it suitable for many homes with 200 Amp electrical service.
Rather than restricting backup power to a small group of predetermined emergency circuits, a service-entrance transfer configuration can provide generator access across the home's electrical system.
However, the 200 Amp rating of the transfer switch should not be confused with generator output. The generator can only supply electrical power up to its rated capacity.
If simultaneous household demand exceeds available generator output, appropriate load management may be required.
Designed for Homes with HVAC Loads
Heating and cooling equipment can represent one of the largest electrical demands in a residential backup-power system.
Central air conditioners, heat pumps, blowers, pumps, and compressors may also have significant startup requirements.
The 22kW PowerProtect generator provides considerably more standby capacity than smaller residential generator systems, making it an option worth considering for homes where HVAC operation is an important backup-power priority.
Actual HVAC compatibility should be determined from the equipment's electrical specifications, including running and starting requirements, rather than HVAC tonnage alone.
Clean Power for Modern Electronics
Modern homes rely on sophisticated electronic equipment throughout the property.
Computers, televisions, Wi-Fi equipment, security systems, smart-home devices, HVAC controls, and modern appliances all contain sensitive electronic components.
The Briggs & Stratton 040795 is specified to produce less than 5% total harmonic distortion (THD), providing stable electrical output for modern residential equipment.
Natural Gas or Liquid Propane
The Briggs & Stratton PowerProtect 22kW can operate on either natural gas or liquid propane vapor.
This dual-fuel capability allows homeowners and installers to select the fuel source most appropriate for the property.
Natural gas can provide a convenient option for homes with an appropriately sized utility gas service, while propane provides an alternative for properties without natural-gas availability.
The generator's fuel supply must be properly sized according to generator demand, fuel type, piping distance, local conditions, and applicable installation requirements.
Built for Outdoor Installation
A standby generator remains exposed to outdoor conditions throughout the year.
The Briggs & Stratton 040795 features a corrosion-resistant aluminum enclosure designed to protect the generator's internal components and provide long-term outdoor durability.
The system is designed for operation across temperatures ranging from approximately -20°F to 104°F, providing year-round standby capability across a wide range of climates.
Quiet Residential Operation
Sound is an important consideration when installing a standby generator near a home or neighboring property.
The supplied specifications list approximately:
| Operating Condition |
Sound Level |
| Low Idle |
64 dBA |
| Normal Operation |
68 dBA |
Actual perceived sound can vary according to installation location, distance, surrounding structures, terrain, and environmental conditions.
Automatic Exercise and Generator Monitoring
Standby generators may go weeks or months without being needed for an actual outage.
A programmable exercise cycle allows the PowerProtect generator to periodically operate and verify system readiness.
The advanced generator controller also provides operating information and diagnostic feedback, helping homeowners and service technicians monitor system condition and identify potential maintenance requirements.

Frequently Asked Questions
Does the Briggs & Stratton 040795 include a transfer switch?
Yes. The Briggs & Stratton 040795 package includes a 200 Amp service-entrance-rated automatic transfer switch.
The transfer switch monitors utility power and automatically manages the transition between utility and generator power during an outage.
Can a 22kW generator power an entire house?
A 22kW standby generator provides substantial capacity for many residential applications, but actual whole-home capability depends on the home's electrical demand.
Homes with multiple HVAC systems, electric heat, electric water heaters, ranges, dryers, pool equipment, pumps, EV chargers, or other large loads may exceed 22kW if several loads operate simultaneously.
Load management may therefore be appropriate for some installations.
What can a 22kW standby generator run?
Depending on total electrical demand and equipment startup requirements, a properly configured 22kW system may support central air conditioning, refrigeration, lighting, pumps, heating equipment, kitchen appliances, electronics, security systems, and numerous other household circuits.
A professional load calculation is the best way to determine which equipment can operate simultaneously.
Can the Briggs & Stratton 040795 run central air conditioning?
Potentially, yes.
Whether the generator can start and operate a particular central air-conditioning system depends on the HVAC equipment's running current, starting requirements, other connected loads, and overall system configuration.
HVAC compatibility should therefore be evaluated using the actual equipment specifications rather than tonnage alone.
What is the advantage of the 200 Amp service entrance transfer switch?
The included 200 Amp SE transfer switch allows the standby-power system to integrate with many residential 200 Amp electrical services instead of restricting generator power to a small number of predetermined circuits.
Generator capacity still determines how much equipment can operate simultaneously.
Does the generator automatically start during an outage?
Yes. When properly installed with the included automatic transfer switch, the system is designed to detect utility failure, start the generator, and automatically transition the electrical system to generator power.
When utility power returns, the system automatically transfers back to the utility source.
Does the Briggs & Stratton 040795 run on natural gas?
Yes. The generator is designed to operate on natural gas or liquid propane vapor.
The selected fuel system must be appropriately sized for generator demand.
Does this generator provide clean power for electronics?
The supplied specifications state that the generator produces less than 5% total harmonic distortion, providing stable electrical output for modern residential electronics and appliances.
How loud is the Briggs & Stratton 22kW generator?
The supplied specifications list approximately 64 dBA in low-idle operation and 68 dBA during normal operation.
Actual sound levels experienced at the property will depend on generator placement and surrounding conditions.
