Briggs & Stratton Standby Generator Guide

The PowerProtect Series

Briggs & Stratton built the PowerProtect line specifically for residential standby power. These air-cooled units run on natural gas or LP propane and start automatically within seconds of detecting a utility outage. No manual intervention required. When the utility restores, the generator shuts off and transfers power back. The PowerProtect series covers a range from 13kW to 26kW, making it a fit for homes of varying sizes.

Choosing Your kW Output

A 13kW unit handles the circuits most homeowners consider essential: refrigerator, lighting, select wall outlets, a sump pump, and a window air conditioner. It is the entry point for meaningful home backup coverage. An 18kW unit steps up to handle a central air system along with those essential loads, making it suitable for homes where keeping the HVAC running is a priority. A 22kW unit extends coverage further, supporting larger HVAC systems and more household circuits simultaneously. The 26kW is the top of the PowerProtect line and suits large homes with higher electrical demand or multiple HVAC zones. Before selecting an output level, have a licensed electrician perform a load calculation. That calculation is the only reliable way to size a generator for a specific home.

Air-Cooled vs. Liquid-Cooled

All PowerProtect models in this range are air-cooled. Air-cooled generators use engine fins and a fan to dissipate heat, keeping the design simpler and the price lower than liquid-cooled alternatives. Liquid-cooled generators are typically found in outputs above 22kW or in commercial applications. For most residential standby needs in the 13-26kW range, air-cooled performance is reliable and sufficient.

Natural Gas vs. Propane

PowerProtect generators run on natural gas or LP propane. Natural gas connects to the existing utility line at your home, so the fuel supply does not run out during an extended outage. This makes it the preferred choice where natural gas service is available. Propane uses a tank installed on the property. It works well in rural areas without gas service, but the tank must be sized adequately for extended run times. Your gas contractor determines the right fuel line size and connection during installation.

How Automatic Transfer Works

An automatic transfer switch (ATS) is the component that makes standby power truly automatic. It monitors the utility feed continuously. When it detects a power loss, it signals the generator to start. Once the generator reaches operating speed and voltage, the ATS opens the utility connection and closes the generator connection, transferring your home to generator power. The process takes seconds. When utility power returns, the ATS reverses the process and the generator cools down before shutting off. Transfer switch options, including Briggs & Stratton Symphony power management systems, are available as bundles with each PowerProtect model.

Installation Requirements

Standby generator installation is not a DIY project. It requires a licensed electrician for the transfer switch and panel connections, a licensed gas contractor for the fuel supply line, and building permits in most jurisdictions. The generator sits on a concrete pad with clearances for ventilation and service access. Permit requirements and setback distances from structures vary by municipality. Plan for installation lead time when ordering, especially during peak demand seasons after major storms.

Routine Maintenance

PowerProtect generators run a weekly self-test exercise cycle automatically. This keeps the engine lubricated and confirms the unit is ready to respond. Annual professional maintenance covers the oil change, spark plug inspection, air filter replacement, battery test, and a functional check of the transfer switch. Following the maintenance schedule in the owner's manual keeps the generator ready and supports warranty coverage. Most homeowners arrange annual service through their installing dealer.

A 13kW unit covers essential circuits: refrigerator, lights, select outlets, and a window air conditioner. A 18kW unit handles a central air system along with essential household loads. A 22-26kW unit provides near-whole-home coverage for larger homes. Work with a licensed electrician for a load calculation specific to your home before purchasing.

Yes. An automatic transfer switch is required. It monitors utility power and signals the generator to start automatically within seconds of an outage. Your installing electrician connects the transfer switch to your home's electrical panel. Transfer switch options are available as bundles with each PowerProtect model.

No. Standby generator installation requires a licensed electrician for the electrical connections and a licensed gas contractor for the fuel line. Building permits are required in most jurisdictions. Attempting a DIY installation voids the manufacturer warranty and creates safety and code compliance risks.

Briggs & Stratton standby generators run a weekly self-test automatically to verify readiness. Annual professional maintenance includes an oil change, spark plug inspection, battery test, and air filter service. Many homeowners schedule annual maintenance through their installing dealer. Refer to the owner's manual for model-specific service intervals.
