Key Features & Benefits
High-Capacity Power Output
With 28,000 peak watts and 20,000 running watts, the WGen20000c is built to support demanding power requirements. It can operate compatible household appliances, workshop equipment, and jobsite tools when their combined starting and running wattage stays within the generator’s limits.
Powerful 999cc V-Twin OHV Engine
The heavy-duty 999cc Westinghouse V-Twin OHV engine provides the power needed for demanding applications. Its design is intended to deliver dependable performance for backup power and portable worksite use.
Convenient Push-Button Electric Start
Get started with the convenient electric-start system, designed to simplify operation without the need for repeated manual pull-starting.
Large 17.17-Gallon Fuel Tank
The 17.17-gallon fuel tank helps support extended operation between refueling stops. Under specified conditions, the generator can run for up to 11 hours at 25% load. Actual runtime varies with connected equipment, load, and operating conditions.
Versatile Power Connections
The generator includes L14-30R and 14-50R outlet configurations for compatible equipment and power applications. These connections can support appropriate transfer-switch installations when the electrical system, outlet ratings, and installation requirements are compatible.
Important: A qualified electrician should verify the required connection, transfer-switch compatibility, and installation procedure before connecting a generator to a home’s electrical system.
Power Quality for Compatible Electronics
With a specified total harmonic distortion (THD) of less than 5%, the WGen20000c is designed to provide relatively clean power for compatible electronic equipment. Always check the requirements of sensitive devices before connecting them.
Integrated Carbon Monoxide Protection
The built-in carbon monoxide (CO) detection system is designed to shut down the generator when dangerous CO levels are detected. This safety feature is an additional safeguard, not a replacement for safe operating practices.
Never operate a gasoline generator indoors, inside a garage, or near doors, windows, or air intakes. Always use it outdoors, well away from occupied buildings, in accordance with the manufacturer’s instructions.
Rugged Steel Frame & Mobility Features
Built for demanding environments, the WGen20000c features a durable steel frame, reinforced handles, and heavy-duty wheels to help with movement and positioning. Its portable design makes it suitable for locations where substantial power is needed.
Digital Monitoring Display
The digital display provides useful operating information, including runtime hours, voltage, and frequency, helping users monitor generator operation and plan routine maintenance.
Essential Setup Accessories
The generator package includes setup accessories such as oil, an oil funnel, a setup guide, and an owner’s manual to help simplify initial preparation. Review the owner’s manual for the complete setup and operating instructions before use.
Warranty & Technical Support
The WGen20000c is listed with a 3-year limited warranty and lifetime technical support. Warranty coverage and eligibility are subject to the manufacturer’s current terms and conditions.
Ideal Applications
The Westinghouse WGen20000c is designed for a variety of high-power applications, including:
- Home backup power: Help keep selected essential appliances operating during an outage.
- Workshops and garages: Supply power for compatible equipment and tools when operated in a safe outdoor setup.
