26000 Watts LP / 24000 Watts NG     7-Year Comprehensive Warranty     Dual ATS for Split Service

NEW Briggs & Stratton 26kW Standby Generator is the most powerful air-cooled standby generator available. Briggs and Stratton’s PowerProtect Series has a sleek and appealing design with tool-less accessibility to all major components for routine maintenance.

NEW Weekly Exercise Test takes just 16 seconds.

NEW Engineered with NGMax Technology. The new standard for more power when running on Natural Gas.

NEW Briggs & Stratton 7-Year Comprehensive Warranty is the Longest in the Industry

More powerful than the competition, Briggs and Stratton rates the air-cooled standby at 26kW for LP Propane and 24kW for Natural Gas. PowerProtect Series generators install just 18 inches from your home, taking up less space and fitting into your landscape. The Briggs & Stratton 40802 includes a Dual 200 Amp/Split 400 Amp Symphony II Automatic Transfer Switch for installation on a 400-Amp or 300-Amp service with two main circuit breaker panels.

The 26kW Briggs and Stratton Generator has the longest, most comprehensive warranty of any air-cooled standby. PowerProtect generators include a comprehensive 7-Year* warranty covering parts, labor, and travel for the entire 7-year term. Made in the USA with commercial-grade Vanguard engines that lead the industry with rugged and reliable operation. With the supplied 400 Amp Split Service Transfer Switch, the 26kW generator keeps your entire home supplied with power for the duration of any power outage.

26kW Briggs and Stratton Generator 400 Amp Split Service Transfer Switch

Homes with split 400-Amp or 300-Amp utility service require a transfer switch that can serve both panels. Some manufacturers make the generator-to-house-connection with a transfer switch for each main panel (two transfer switches.) The Briggs & Stratton 400 Amp Split Service Transfer Switch implements both switches into a single package, simplifying installation for a cleaner, neater appearance.

The 26kW Briggs and Stratton Generator restores power to your home during utility outages. Fully automatic, it works in any weather including hurricanes, Whether you’re at home, away on vacation, or sleeping in your bed, the 26kW generator senses a power outage. Within seconds, the generator starts and signals the automatic transfer switch. The ATS switches from utility to generator power. The Symphony II power management system allows you to prioritize the most important heavy loads by their importance.

This 26kW Briggs and Stratton Generator includes the Symphony II 400 Amp Split Service Automatic Transfer Switch with a Service Entrance Rated Disconnect (SED.)

Symphony II Power Management controls up to eight circuits with low voltage modules, dual low voltage modules, and 50-amp line voltage modules. Module priority is set during installation. Your installer will determine the appropriate modules to use when planning the installation.

Briggs and Stratton 26kW Generator

The Briggs and Stratton 26kW Generator has a 993 cc V-Twin OHV Vanguard commercial-grade engine equipped with Low Oil Shutdown to prevent engine damage.
