Description

Zoom on the Westinghouse WGen12000DF

In summary, the Westinghouse WGen12000DF is a powerful portable generator especially useful for:

  • 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 WGen12000DF in use

The Westinghouse WGen12000DF

The dual-fuel technology of the Westinghouse WGen12000DF allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 12000W and a starting wattage of 15000W. If propane-powered, it gives 10800 rated watts and 13500 starting watts.

With a noise rating of 74 dBA (just slightly more noisy than a dishwasher), the generator features a convenient and easy-to-use electric starter (battery included). Moreover, to offer you even more convenience, the WGen12000DF can also be remotely started (key fob included).

With a fuel capacity of 10.5 gallons, the WGen12000DF can operate for up to 16 hours using gasoline (fuel consumption around 0.95 GPH), or for up to 10 hours (on a 20 lbs tank - propane consumption around 0.47 GPH) using propane.

Sensitive electronics can be safely plugged in the AC outlets, as the WGen12000DF produces a clean sine wave, with a <5% Total Harmonic Disruption (THD).

Outlets

The control panel features the upcoming 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

Additionally, it features 2 DC outlets: there's two 5V USB ports allowing you to conveniently charge electronics such as mobile phones and tablets.

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, because the WGen12000DF is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.

Westinghouse's ST Switch Outlet

Picture of the ST Switch outlet

The ST Switch outlet

The WGen12000DF 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 WGen12000DF 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 WGen12000DF offers stability and allows the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

Since the generator weighs 352 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, 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.

A lift hook located on the top of the frame offers an additional safety feature while facilitating the transport, loading and unloading of the generator.

Features

Panel of the Westinghouse WGen12000DF

The WGen12000DF's control panel

The WGen12000DF's control center features a convenient meter showing you voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

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

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Westinghouse WGen12000DF's package also includes these accessories: funnel, oil, battery charger, key fob, propane hose and tool kit.

Emissions

The Westinghouse WGen12000DF is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor and therefore, can be used in forested areas.

The Westinghouse WGen12000DF versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Westinghouse WGen12000DF compare to generators of similar power (between 10000 and 14000 W).

  • Considering its dry weight of 352 pounds, the Westinghouse WGen12000DF is one of the heavier generators producing between 10000 and 14000 running watts. If you are concerned by weight, one of the champions in the above mentioned power range is the A-iPower SUA13000EFI, with a dry weight of 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. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the A-iPower SUA13000EFI, whose lowest noise levels reach just 69 dBA.
  • As the WGen12000DF offers around 11 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the generators of a similar power. 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.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. 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 you are concerned with gasoline efficiency, having a fuel consumption of just 0.78 GPH, the A-iPower SUA13000EFI is a device you should look out for.

Price comparison

As you can see from this interactive chart, when compared to other 10000-14000W generators, the Westinghouse WGen12000DF 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.

Does the WGEN12000DF generator have a backup recoil starter? Does the above model utilize an oil filter and what is the part number? (Asked August 06, 2020)

The V-Twin engine of the WGen12000DF does not have a backup recoil starter. The unit does utilize an oil filter, part number 180738.

Are the household receptacles (5-20R) the only receptacles with GFCI Protection? If the neutral is changed from bonded to floating, will the household receptacle's GFCI still function properly? (Asked October 16, 2020)

Correct. Only the two 5-20R duplexes are with GFCI protection. Removing the bonded neutral may not allow proper operation of the GFCI receptacles.
