Backup Power for Homes with Multiple Electrical Panels

The major difference between the Briggs & Stratton 040794 and a conventional single-transfer-switch package is the inclusion of two 200 Amp service entrance transfer switches.

Some larger homes and properties have multiple electrical panels or electrical-service configurations that require more than one transfer switch.

The dual-transfer-switch configuration provides installers with additional flexibility when integrating the standby generator into these electrical systems.

This can make the 040794 particularly useful for properties with:

  • Multiple main electrical panels
  • Expanded residential electrical systems
  • Large homes with distributed electrical loads
  • Compatible multi-panel service configurations
  • Properties where a single transfer switch does not meet the installation requirements

The appropriate configuration should always be determined from the property's actual electrical-service design.

Important: Dual 200 Amp Transfer Switches Do Not Mean 400 Amps of Generator Power

The two transfer switches determine how electrical loads can be transferred between utility and generator power. They do not increase the electrical output of the generator.

The Briggs & Stratton 040794 remains a 22kW generator.

For example, a property may have two electrical panels connected through the appropriate transfer configuration, but the combined electrical demand placed on the generator must remain within the generator's available capacity.

If potential demand exceeds generator capacity, load management may be necessary to prevent excessive loads from operating simultaneously.

Automatic Backup Power During an Outage

When utility power is operating normally, the home's electrical system receives electricity from the utility.

If an outage occurs, the automatic transfer system detects the loss of utility power and initiates generator startup.

Once the PowerProtect generator is ready to supply electricity, the transfer system transitions the appropriate electrical loads from utility power to generator power.

When utility service returns, the transfer system moves the electrical loads back to utility power and the generator completes its shutdown sequence.

This automatic process allows the standby-power system to respond whether you're home or away.

22kW of Residential Standby Power

With 22kW of standby capacity, the Briggs & Stratton 040794 is designed for homes with substantial backup-power requirements.

Depending on individual equipment requirements and total electrical demand, a properly configured system may support equipment 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
  • Essential circuits across multiple electrical panels

The amount of equipment that can operate simultaneously depends on the combined running and starting requirements of the connected loads.

Designed for HVAC and Motor Loads

Central HVAC equipment can represent one of the largest electrical demands in a home.

Air conditioners, heat pumps, compressors, pumps, and other motor-driven equipment may require significantly more power during startup than during normal operation.

The PowerProtect 22kW provides substantial residential standby capacity, making it suitable for consideration when maintaining heating and cooling is an important backup-power objective.

Actual HVAC compatibility should be determined using the equipment's electrical specifications and starting requirements rather than tonnage alone.

Clean Power for Modern Homes

Modern residential electrical systems contain sensitive electronic components throughout the home.

Computers, televisions, Wi-Fi equipment, security systems, smart-home devices, HVAC control boards, and modern appliances all benefit from stable electrical power.

The Briggs & Stratton 040794 is specified to produce less than 5% total harmonic distortion (THD), providing stable electrical output for modern household equipment.

Natural Gas or Liquid Propane Operation

The Briggs & Stratton PowerProtect 22kW is designed to operate on either natural gas or liquid propane vapor.

Natural gas may be convenient for properties already connected to an appropriately sized utility gas service, while propane provides another option for properties without natural-gas availability.

The fuel supply must be properly sized according to generator demand, fuel type, piping distance, pressure, local conditions, and installation requirements.

Durable Outdoor Construction

Because standby generators remain outdoors throughout the year, enclosure construction is an important consideration.

The Briggs & Stratton 040794 features a corrosion-resistant aluminum enclosure designed to protect the generator's internal components from outdoor conditions.

The supplied specifications also identify a high-wind-rated enclosure design, making the system suitable for consideration in areas where severe-weather installation requirements are important.

The generator is designed to operate across temperatures ranging from approximately -20°F to 104°F.

Quiet Residential Operation

The supplied specifications list the following approximate operating sound levels:

Operating Condition Sound Level
Low Idle 64 dBA
Normal Operation 68 dBA

Actual perceived sound will vary depending on generator placement, distance, nearby structures, terrain, and installation conditions.

Automatic Exercise and System Monitoring

A standby generator may remain unused for extended periods between utility outages.

The PowerProtect system includes a programmable exercise cycle, allowing the generator to periodically operate and help verify system readiness.

Its advanced controller also provides operating information, diagnostic feedback, and system status information for homeowners and service professionals.
