Briggs & Stratton PowerProtect+™ DX 18kW Home Standby Generator
The PowerProtect+™ DX 18kW (model 040760) brings premium-tier performance to mid-size homes. With best-in-class starting power engineered to start a 5-ton air conditioner, it keeps your central air running through summer outages — a job many competing 18kW units can’t handle. Full 18kW output on both natural gas and propane means no power penalty on NG.
