Can it power a whole house?

With 20,000 running watts and a transfer switch, it can carry a typical home's major loads, including a 5-ton air conditioner, refrigerator and sump pump at once.

Does it need a transfer switch?

The L14-30R outlet is transfer-switch ready. A transfer switch is the safe way to connect it to home wiring; the 14-50R outlet can feed a panel or large load directly.

It is rated 74 dBA, which is loud for a neighborhood. Expect noticeable noise under heavy load.

It weighs about 541 lb. The wheels and handles help on flat ground, but loading it into a truck needs ramps and help or equipment.

Is it safe for electronics?

Yes. Its outlets produce under 5% total harmonic distortion, so phones, TVs and computers can be charged directly from the panel.

What comes in the box?

The generator, a remote start fob, heavy-duty wheels, quick-release handles and lift brackets. It carries a 3-year limited warranty.

About the Westinghouse WGen20000c 20000W Gas Powered Portable Generator

The Westinghouse WGen20000c is a portable gas generator rated for 20,000 running watts and 28,000 peak watts. It has a 999 cc Westinghouse V-Twin OHV engine with a cast iron sleeve. The 17.17-gallon (65 L) fuel tank has a built-in fuel gauge and gives up to 14 hours of run time at 25% load.

It starts with a push button or a remote fob. The panel has a choke knob and a fuel control valve. The generator shuts down automatically on low oil or carbon monoxide (CO). Idle control is included. A VFT data center shows lifetime run hours, volts and frequency.

The outlets include Transfer Switch Ready L14-30R and 14-50R outlets, which can power major appliances such as an air conditioner, refrigerator and sump pump with a single cord hookup. The outlets produce less than 5% THD, so sensitive electronics can be charged directly from the control panel. A steel frame with lift brackets, heavy-duty wheels and reinforced handles with quick-release pins make it portable.
