Description

Zoom on the Westinghouse WGen12000

In a nutshell, the Westinghouse WGen12000 is a powerful portable generator mostly geared towards:

  • Professionals in need of safely powering high-intensity work or lighting equipment
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Westinghouse WGen12000 in use

The Westinghouse WGen12000

The Westinghouse WGen12000's engine, 713 cc (22 hp) Westinghouse V-Twin, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 12000W and reaches a peak wattage of 15000W.

Enjoying a noise rating of 74 dBA (just slightly more noisy than a vacuum cleaner), this generator gets running thanks to a convenient and easy-to-use electric starter (battery included). Moreover, to offer you even more convenience, the WGen12000 can also be remotely started (key fob included).

With a fuel capacity of 10.5 gallons, the WGen12000 may run for up to 16 hours with a full tank (fuel consumption around 0.95 GPH).

The WGen12000 produces a clean sine wave: thanks to a <5% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel features the following 7 AC outlets:

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

Furthermore, it has 2 DC outlets: there's two 5V USB ports with which you may charge electronics, for example mobile phones or tablets, conveniently.

While this Westinghouse generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor. Besides, as it features a twist-lock L14-30R receptacle, the WGen12000 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 WGen12000 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 WGen12000 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

With its dimensions of L34 x W31 x H35 in, the conventional, open frame design of the Westinghouse WGen12000 offers stability and allows the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

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 352 lbs. Nevertheless, thanks to its wheel kit and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed 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 WGen12000's control panel

The WGen12000'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.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Westinghouse WGen12000 also is packed along with the following accessories: battery charger, oil, tool kit, key fob and funnel.

Emissions

The Westinghouse WGen12000 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

The Westinghouse WGen12000 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Westinghouse WGen12000 compare to generators of similar power (between 10000 and 14000 W).

  • With its weight of 352 lbs, the Westinghouse WGen12000 is one of the heavier generators in the 10000-14000 rated wattage category. If weight is your top priority, one of the champions in this power category is the A-iPower SUA13000EFI, weighing just 218 pounds.
  • With a lowest noise rating of 74 dBA, the generator is one of the more quiet of the generators of similar power. For those who are looking for a less noisy device, we suggest the A-iPower SUA13000EFI. With just 69 dBA, it is one of the most quiet devices in this power range.
  • The WGen12000, falls within the average autonomy range compared to generators of a roughly same power, with a run time of around 11 hours at a 50% load and a full tank. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Powerhorse 13000ES, with around 15 hours.
  • 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. At an estimated fuel consumption of 0.95 GPH (gallon per hour) at 50% load, this generator is a rather fuel efficient one within its wattage category. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the A-iPower SUA13000EFI. With a fuel consumption of as little as 0.78 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 10000-14000W generators, the Westinghouse WGen12000 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 – which are the main product of the Outdoor Power Equipment branch of Westinghouse. 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, several sources report that they are in many cases manufactured in China.

Warranty Information
