Description

Zoom on the Westinghouse WGen20000c

In summary, the Westinghouse WGen20000c is a powerful portable generator especially useful for:

  • Professionals who want to be able to deliver results, even during a power failure
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Westinghouse WGen20000c in use

The Westinghouse WGen20000c

The Westinghouse WGen20000c's design includes a gasoline-fueled 999 cc OHV V-Twin engine. With a 120/240V output, it gives a running wattage of 20,000W and also a peak wattage of 28,000W.

With a noise rating of 74 dBA (just slightly more noisy than a dishwasher), the generator features a simple and elegant electric starter (battery included). To add further convenience, the WGen20000c can be remotely started (key fob included).

The WGen20000c can operate for around 11 hours at 50% load with a full tank (fuel consumption around 1.56 GPH), due to its fuel capacity of 17.17 gallons.

Delicate electronics can be plugged in an AC outlets safely, as the WGen20000c generates a clean sine wave, reaching a <5% Total Harmonic Distortion (THD).

Outlets

The control panel features the upcoming 7 AC outlets:

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

Even though this Westinghouse generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor. Besides, as it features a twist-lock L14-30R receptacle, the WGen20000c is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

Westinghouse's ST Switch Outlet

Picture of the ST Switch outlet

The ST Switch outlet

The WGen20000c 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 WGen20000c 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

The Westinghouse WGen20000c has the following dimensions: L38 x W35 x H40.4 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

Since the generator weighs 541.1 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀13") and its folding handle, once it is placed 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 WGen20000c's control panel

The WGen20000c's status and activity may be monitored conveniently via the control panel, as it features a convenient meter, which displays voltage, frequency and lifetime hours.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

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.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Westinghouse WGen20000c also is packed along with the following accessories: tool kit, key fob, funnel and oil.

Emissions

The Westinghouse WGen20000c is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor, so it is adequate for use in forested areas.

The Westinghouse WGen20000c versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Westinghouse WGen20000c compare to generators of similar power (between 14000 and 20000 W).

  • With its weight of 541.1 lbs, the Westinghouse WGen20000c is one of the heavier generators in the 14000-20000 rated wattage category. If weight matters to you, one of the champions in this power range is the Generac GP15000E with only 363 pounds.
  • The WGen20000c provides one of the highest run time among similarly powerful devices, reaching around 11 hours at 50% load.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. As this generator uses an estimated 1.56 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you wish to acquire one of the most gasoline efficient products of this power range, the Generac GP15500EFI, with a fuel consumption of 1.29 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 14000-20000W generators, the Westinghouse WGen20000c is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

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.
