Description

Zoom on the Westinghouse WGen12000

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

  • Professionals who want to ensure that a power failure will not prevent them from working
  • 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 WGen12000 in use

The Westinghouse WGen12000

The Westinghouse WGen12000 is powered by a 713 cc (22 hp) Westinghouse V-Twin engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 12000W as well as a peak wattage of 15000W.

The generator features a simple and elegant electric starter (battery included). It is rated for a noise of 74 dBA (just slightly more noisy than a dishwasher). The WGen12000 can also be remotely started, offering further convenience (key fob included).

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

Sensitive electronics can be safely plugged in the AC outlets, as the WGen12000 produces a clean sine wave, with a <5% Total Harmonic Disruption (THD).

Outlets

The control panel includes 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

It also sports 2 DC outlets: there's two 5V USB ports with which charging of electronics like mobile phones and tablets is made convenient.

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, because the WGen12000 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 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

The Westinghouse WGen12000 has a conventional, open frame design, of the following dimensions: L34 x W31 x H35 in, which offers support and allows it to be raised above ground level. The design is ideal for rough 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 352 lbs. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit and its folding handle, once it is placed on the ground.

A lift hook, which is on the top of the frame, serves as an extra safety feature for the transport, unloading and loading of the device.

Features

The WGen12000's control panel

The control panel of the WGen12000 includes a convenient meter showing you voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Westinghouse WGen12000's package also includes these accessories: key fob, tool kit, oil, battery charger and funnel.

Emissions

The Westinghouse WGen12000 is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor, so it is adequate for use 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).

  • As its dry weight is 352 pounds, the Westinghouse WGen12000 is one of the heavier of the products which can generate 10000 to 14000 running watts. 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. 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 WGen12000 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 concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Powerhorse 13000ES, boasting 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. With an estimated gasoline consumption of 0.95 GPH (gallon per hour) at 50% load, this generator is among the more fuel efficient of the products in the above-mentioned wattage range. If you wish to acquire one of the most gasoline efficient products of this power range, the A-iPower SUA13000EFI, with a fuel consumption of 0.78 GPH could be in your good books.

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

The Westinghouse WGen12000 is covered under a warranty for up to 3 years. This warranty may be limited and may not cover all parts of the generator.
