Briggs & Stratton 040765 18kW PowerProtect™ Generator with 200 Amp SE Transfer Switch
The Briggs & Stratton 040765 18kW PowerProtect™ generator with 200A service entrance transfer switch is a complete home standby power solution designed to provide automatic whole-home backup during power outages. This system combines a reliable 18kW standby generator with an integrated 200-amp transfer switch, allowing it to seamlessly take over your home’s electrical system within seconds of a utility interruption.
With 18kW of standby power and 120/240-volt single-phase output, this generator is capable of powering most medium to large homes, including HVAC systems, refrigerators, lighting, sump pumps, and essential appliances. The included 200A service entrance rated transfer switch allows for full-home power management, making it an ideal choice for homeowners looking for a true whole-house backup solution rather than partial circuit coverage.
At the core of the PowerProtect™ system is a Briggs & Stratton Vanguard® V-twin engine, engineered for long-term durability and consistent standby performance. Operating at 3,600 RPM with a full pressure lubrication system, the engine is designed to handle extended outages while maintaining reliability. The generator also delivers less than 5% total harmonic distortion (THD), ensuring clean, stable electricity that is safe for sensitive electronics and modern home systems.
Built for outdoor installation, the generator features a corrosion-resistant aluminum enclosure and operates at sound levels as low as 64 dB in low idle mode and 68 dB during normal operation, making it suitable for residential environments. The system includes advanced controls with programmable exercise cycles, real-time monitoring, and diagnostic feedback, ensuring the generator is always ready when needed.

Frequently Asked Questions
What is the benefit of a 200A service entrance transfer switch?
A 200A service entrance transfer switch allows the generator to power your entire home rather than just selected circuits. It automatically transfers power from the utility to the generator during an outage and back again when power is restored.
What can an 18kW generator with a 200A transfer switch power?
An 18kW generator paired with a 200A transfer switch can power most homes, including HVAC systems, appliances, lighting, and essential circuits. Load management may still be required depending on total demand.
Is this a complete standby generator system?
Yes. The Briggs & Stratton 040765 includes both the 18kW generator and a 200A transfer switch, making it a complete whole-home backup power solution.
Does this generator produce clean power for electronics?
Yes. The generator produces less than 5% total harmonic distortion, delivering stable power that is safe for sensitive electronics such as computers, TVs, and smart home systems.
What fuel does the generator use?
The generator operates on natural gas or liquid propane vapor, allowing flexibility depending on available fuel sources.
How loud is the generator?
The generator operates at approximately 64 dB in low idle mode and 68 dB during normal operation, making it relatively quiet for a residential standby generator.
