Protect your home from unexpected power outages with the Briggs & Stratton 040765 18kW PowerProtect™ Standby Generator with 200 Amp Service Entrance Transfer Switch. Designed as an automatic residential backup-power solution, this package combines an 18kW standby generator with a 200 Amp service-entrance-rated automatic transfer switch for a streamlined whole-home installation.

Delivering 120/240V single-phase power, the PowerProtect 18kW is designed to support the electrical demands of many medium to larger homes. Depending on the home's total load and system configuration, it can provide backup power for heating and cooling equipment, refrigeration, lighting, pumps, household appliances, electronics, and other important circuits.

At the heart of the system is a Briggs & Stratton Vanguard® V-Twin engine, engineered for dependable standby operation. Combined with full-pressure lubrication, automatic controls, dual-fuel capability, and a durable aluminum enclosure, the 040765 is built for homeowners who want reliable backup power without having to manually start and connect a portable generator during an outage.

Key Features

  • 18kW Standby Power: Provides substantial backup capacity for residential applications.
  • 200 Amp SE Transfer Switch Included: Service-entrance-rated automatic transfer switch provides automatic transition between utility and generator power.
  • 120/240V Single-Phase Output: Designed for standard residential electrical systems.
  • Automatic Standby Operation: Detects a utility interruption through the transfer system and automatically starts the generator when backup power is required.
  • Vanguard® V-Twin Engine: Briggs & Stratton commercial-grade engine technology designed for dependable standby performance.
  • 3,600 RPM Operation: Engineered for residential standby-generator applications.
  • Full-Pressure Lubrication: Helps provide consistent engine lubrication and protection during operation.
  • Natural Gas or Liquid Propane: Dual-fuel capability provides flexibility based on the home's available fuel source.
  • Less Than 5% THD: Produces stable power with low total harmonic distortion for today's household electronics and electrical equipment.
  • Quiet Residential Operation: Rated at approximately 64 dBA during low-idle operation and 68 dBA during normal operation.
  • Programmable Exercise Cycles: Allows the generator to periodically exercise itself so the system remains ready for an outage.

  • Wide Operating Temperature Range: Designed for operation in temperatures ranging from approximately -20°F to 104°F.
  • Corrosion-Resistant Aluminum Enclosure: Helps protect the generator from outdoor environmental conditions.
  • UL and cUL Listed: Designed and tested to applicable safety standards.
  • 6-Year Limited Warranty: Backed by Briggs & Stratton limited warranty coverage.

Automatic Backup Power When the Utility Goes Down

A permanently installed standby generator provides a very different experience from relying on a portable generator during an outage.

When normal utility power is interrupted, the 200 Amp automatic transfer switch detects the outage and signals the PowerProtect generator to start.

Once the generator is ready to supply electricity, the transfer switch automatically transitions the home's electrical system from utility power to generator power.

When utility service returns, the process is reversed and the home is transferred back to utility power.

The result is an automatic backup-power system capable of responding even when you're away from home.

18kW of Residential Standby Power

The Briggs & Stratton 040765 provides 18kW of standby power, giving homeowners substantial capacity for protecting important household systems during an outage.

Depending on the home's electrical demand, a properly configured 18kW standby system may support equipment such as:

  • Central air-conditioning equipment
  • Heating systems
  • Refrigerators and freezers
  • Sump and well pumps
  • Lighting
  • Internet and networking equipment
  • Security systems
  • Garage-door equipment
  • Kitchen appliances
  • TVs and household electronics
  • Selected receptacles and household circuits

Actual capacity depends on the combined running and starting requirements of the connected equipment.

Large loads such as central air conditioners, electric water heaters, ranges, dryers, pumps, and other motor-driven equipment should be considered when sizing the generator.

200 Amp Service Entrance Transfer Switch Included

The included 200 Amp service entrance transfer switch is a major advantage of this PowerProtect package.

The transfer switch continuously monitors utility power and automatically manages the transition between utility and generator power.

A 200 Amp service-entrance configuration can be integrated into many residential electrical systems without limiting the installation to a small predetermined group of emergency circuits.

However, having a 200 Amp transfer switch does not mean an 18kW generator can simultaneously supply 200 amps of generator power. Generator capacity remains limited by the generator's rated output.

For homes with larger electrical demands, appropriate load management may be necessary.

Designed for HVAC and Motor Loads

Heating and cooling equipment can represent some of the largest electrical loads in a home.

Electric motors and compressors can also require substantially more electricity during startup than during normal operation.

The Briggs & Stratton PowerProtect 18kW is designed for residential standby applications where motor-starting capability is an important consideration.

When planning to operate central air-conditioning equipment from a standby generator, the HVAC system's actual running and starting requirements should be evaluated during generator sizing.

Clean Power for Modern Homes

Today's homes contain significantly more sensitive electronics than homes did just a few decades ago.

Computers, televisions, networking equipment, smart-home devices, appliance control boards, HVAC electronics, and security equipment all depend on stable electrical power.

The Briggs & Stratton 040765 produces less than 5% total harmonic distortion (THD), providing stable power suitable for modern residential electrical loads.

Natural Gas or Liquid Propane

The PowerProtect 18kW is designed to operate using either natural gas or liquid propane vapor, giving homeowners flexibility when selecting a fuel source.

Natural gas can be convenient for properties already connected to a properly sized utility gas service, while propane can provide an alternative for homes without natural-gas availability.

Fuel selection and supply sizing should be based on generator demand, available infrastructure, expected runtime, local conditions, and applicable installation requirements.

Built for Outdoor Installation

Standby generators remain outdoors throughout the year, making enclosure construction an important consideration.

The Briggs & Stratton 040765 features a corrosion-resistant aluminum enclosure designed to protect the generator's internal components while providing long-term outdoor durability.

The generator is designed to operate across temperatures ranging from approximately -20°F to 104°F, helping provide year-round standby-power capability across a variety of climates.

Quiet Residential Operation

Generator noise can be particularly important when equipment is installed near a home or neighboring property.

The PowerProtect 18kW operates at approximately:

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

Actual perceived sound will vary according to generator placement, surrounding structures, distance, terrain, and installation conditions.

Automatic Exercise and System Monitoring

A standby generator must remain ready even after months without a utility outage.

Programmable exercise cycles allow the PowerProtect system to periodically operate and verify generator readiness.

The generator's controller also provides system information and diagnostic feedback, helping homeowners and service professionals identify operating conditions and maintenance requirements.

Frequently Asked Questions

Does the Briggs & Stratton 040765 include a transfer switch?

Yes. This package includes a 200 Amp service entrance rated automatic transfer switch, providing the equipment needed to automatically transition a compatible residential electrical system between utility and generator power.

Can an 18kW generator power an entire house?

It depends on the home's electrical demand.

An 18kW generator can provide substantial backup capacity for many homes, but a 200 Amp transfer switch does not mean the generator can simultaneously operate every electrical load connected to a 200 Amp electrical service.

Homes with large air conditioners, electric heat, electric water heaters, ranges, dryers, pumps, or other high-demand equipment may require load management.

Can this generator run central air conditioning?

Potentially, yes. The ability to start and operate a particular air-conditioning system depends on the HVAC equipment's running and starting electrical requirements as well as the other loads being powered simultaneously.

Generator sizing should therefore be based on the actual HVAC equipment specifications rather than tonnage alone.

Does the generator run on natural gas?

The fuel system must be properly sized for the generator's requirements.

Does the generator automatically start during an outage?

Yes. When installed with the included automatic transfer switch, the system is designed to detect a utility outage, start the generator, and automatically transfer the appropriate electrical loads to generator power.

When utility service returns, the transfer switch returns the electrical system to utility power.

Does the Briggs & Stratton 040765 provide clean power?

The supplied specifications state less than 5% total harmonic distortion (THD), providing stable electrical output suitable for modern residential equipment and electronics.

How loud is the Briggs & Stratton 18kW generator?

The supplied specifications list approximately 64 dBA at low idle and 68 dBA during normal operation.
