Power & Run Time

The Westinghouse WGen20000TFc in use

The Westinghouse WGen20000TFc

The Westinghouse WGen20000TFc delivers 120/240V and boasts with a tri-fuel technology enabling it to utilize gasoline, propane, or natural gas. When powered by gasoline, it achieves a running wattage of 20,000W and a peak wattage of 28,000W. Upon using propane, it gains 18,000 rated watts and 25,500 peak watts. Its operation with natural gas provides 16,000W of rated wattage and 22,400W of starting wattage.

Featuring a noise rating of 79 dBA (less noisy than a dishwasher), the generator utilizes a no-fuss and convenient electric starter (battery included) for ignition. Additionally, the WGen20000TFc features remote starting, offering users increased convenience (key fob included).

The WGen20000TFc, with a fuel capacity of 17.17 gallons, reaches a run time of around 10.5 hours at 50% load utilizing gasoline (fuel consumption around 1.64 GPH). Alternatively, it can reach a run time of around 2.5 hours (on a 20 lbs tank - propane consumption around 1.88 GPH) with propane.

The WGen20000TFc generates a clean sine wave with <5% Total Harmonic Distortion (THD), ensuring minimal electrical noise and fluctuations. This feature makes it ideal for powering sensitive electronics, providing stable and reliable AC power through the outlets.

Outlets

The control panel features the following 9 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
Two 120/240V 30A (L14-30R) receptacles
Two 120/240V 50A (14-50R) receptacles

Despite not meeting the 'RV Ready' criteria, this Westinghouse generator grants the advantage of simple RV compatibility via its L5-30R receptacle, enabling you to conveniently power your RV by using an L5-30P to TT-30R adaptor. Besides, since the WGen20000TFc bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Westinghouse's ST Switch Outlet

The ST Switch outlet

The WGen20000TFc is what Westinghouse calls Smart Switch Ready. This means that it features a special outlet that allows for an automatic transfer of power in case of a power outage.

To benefit from this feature, you'll need the Westinghouse ST Switch (opens in a new tab), which is not included with the generator.

Simply put, the ST Switch is a cost-effective and versatile portable automatic transfer switch, which can be installed quickly and easily, without an electrician.

Plug the ST Switch into one of your household 120V outlets, plug your appliances to the ST Switch, and connect the WGen20000TFc to the ST Switch via the special outlet and a 120V cord. The generator will automatically turn on when the power goes out, and automatically turn off when the power returns.

Portability

At L38 x W35 x H40.4 in, the Westinghouse WGen20000TFc boasts a traditional open frame structure, ensuring stability and allowing for convenient maintenance access to components, promoting air circulation. The device has been designed for tough environments and demanding outdoor use.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 557 lbs. However, the limited maneuverability is remedied with its wheel kit (⌀13") and its folding handle, facilitating convenient shifting once the generator is positioned on the ground.

In addition, the device is equipped with a lift hook on the top of its frame, which provides extra safety during the loading, unloading and transport of the generator.

Features

The WGen20000TFc's control panel

To facilitate status and activity monitoring, a convenient meter, offering voltage, frequency, and lifetime hours readings are embedded in the control panel of the WGen20000TFc.

Equipped with a built-in fuel gauge, the generator facilitates swift gas level checks.

From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.

It also includes a carbon monoxide sensor. This sensor is designed to monitor the level of carbon monoxide present during the generator's operation. If the generator is positioned incorrectly and carbon monoxide levels rise to an unsafe level, the generator will automatically shut down.

In addition to the traditional documentation and an owner's manual (opens in a new tab) to help you get started promptly, the Westinghouse WGen20000TFc also includes several accessories: oil, natural gas hose with NPT adapter, propane hose, tool kit, funnel, key fob and battery charger.

The Westinghouse WGen20000TFc versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Westinghouse WGen20000TFc compare to generators of similar power (between 14000 and 22000 W).

  • A weight of 557 lbs makes the Westinghouse WGen20000TFc one of the heaviest devices in the 14000-22000 rated wattage range. If you are concerned by weight, one of the champions in the above-mentioned power range is the Pulsar PGD170TiSRCO, with a dry weight of just 313 pounds.
  • Because this generator emits noise as low as 79 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If you wish to prioritize minimal noise, the Pulsar PGD170TiSRCO stands out as one of the quietest options among generators of similar power, with a rating of 66 dBA.
  • In terms of run time, the WGen20000TFc surpasses similarly powerful devices, boasting one of the higher run times at around 10.5 hours. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Westinghouse WGen20000, reaching around 11 hours.
  • Run time is a key metric, but it's dependent on the generator's fuel tank capacity. Therefore, discussing fuel efficiency is necessary for a complete understanding. When it comes to fuel efficiency among generators with similar wattage, this generator lags behind, with a consumption rate of 1.64 GPH at a 50% load. If you wish to get a unit of similar power, but with one of the best fuel efficiency, you could consider the Westinghouse WGen14500DFc, which has an impressively low fuel consumption of 0.95 GPH.

About Westinghouse

The US based Westinghouse Outdoor Power Equipment is a legacy subsidiary of the Westinghouse Electric Corporation, founded in 1886. While the company has been acquired and merged into the American CBS, the Westinghouse name remains as the brand name for many of their electrical solutions, which stretch across the scale from power plants to portable generators. Portable generators – the main product of the Outdoor Power Equipment branch of Westinghouse – used to be manufactured by Westpro Power Systems, which was bought in 2016 by Midwest Equipment. Lawn equipment, such as trimmers and blowers, is also sold under the Westinghouse brand name. All of their products are designed in the US. However, they are in many cases manufactured in China and Vietnam.

Article states "...offers around 2.5 hours (on a 20 lbs tank - propane consumption around 1.88 GPH) of operation when using propane." Most 20lbs propane tanks are filled with 15lbs now. Was the 1.8 GPH calculated off of 20Lbs of propane or 15? (Asked July 18, 2024)

Since these are the manufacturer's values, it's fairly safe to assume that they want them to look as good as possible, and that the tank was as full as it can be.

do i need natural gas conversion kit for using natural gas? (Asked June 11, 2025)

The unit is tri fuel, and supports natural gas out of the box

Can I switch fuel types with the generator running? (Asked April 25, 2026)

The fuel source can be switched while the engine is off or while it is running if a propane tank or natural gas supply line is connected to the generator BEFORE operation. If switching from gasoline to another fuel source while the engine is running, it may run rough for a few seconds as it purges gasoline from the carburetor.
