Briggs & Stratton 040794 22kW PowerProtect+ Generator with Dual 200A SE Transfer Switch Features:
Briggs & Stratton 040794 22kW PowerProtect™ Generator with Dual 200 Amp SE Transfer Switches
The Briggs & Stratton 040794 22kW PowerProtect™ generator with dual 200A service entrance transfer switches is a complete whole-property backup power solution designed for homes with multiple electrical panels or larger service requirements. This system combines a high-capacity 22kW standby generator with two 200-amp transfer switches, allowing seamless and automatic power transfer across multiple panels during a utility outage.
With 22kW of standby power and 120/240-volt single-phase output, this system is designed to support large homes, multi-panel electrical systems, and properties with expanded electrical infrastructure. The inclusion of dual 200A service entrance transfer switches makes it ideal for homes with separate main panels, detached structures, or high electrical demand setups where a single transfer switch would not provide full coverage.
At the core of the system is a Briggs & Stratton Vanguard® V-twin engine, engineered for durability and long-term standby performance. Operating at 3,600 RPM with a full pressure lubrication system, the engine is built to handle extended outages while maintaining consistent power output. The generator produces less than 5% total harmonic distortion (THD), delivering clean, stable electricity that protects sensitive electronics and modern home systems.
Designed for outdoor installation, the generator features a corrosion-resistant aluminum enclosure with a high wind rating 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 also includes an advanced controller with programmable exercise cycles, real-time monitoring, and diagnostic capabilities to ensure the generator is always ready when needed.
