Description

Zoom on the Westinghouse WGen12000

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

  • Professionals who want to be able to deliver results, even during a power failure
  • Homeowners in need of an emergency backup power for their essentials

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 houses a 713 cc (22 hp) Westinghouse V-Twin engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 12000W along with a peak wattage of 15000W.

The generator features a convenient and easy-to-use electric starter (battery included). It is rated for a noise of 74 dBA (just slightly more noisy than a shower). For additional convenience, the WGen12000 may also be remotely started (key fob included).

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

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

In addition, it provides 2 DC outlets: there's two 5V USB ports with which charging of electronics like mobile phones and tablets is made convenient.

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

The design of the Westinghouse WGen12000 is a typical, open frame, with the dimensions of L34 x W31 x H35 in, offering support and stability and enabling the possibility of raising it above ground level. This type of design is ideal for tough environments and heavy outdoor use.

As the generator's weight is 352 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

The generator comes with an additional safety feature, a lift hook on the top of its frame, which is helpful during its transport, loading and unloading.

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 showing you voltage, frequency and lifetime hours.

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

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

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Westinghouse WGen12000 also comes with several accessories, including: oil, funnel, battery charger, tool kit and key fob.

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, which makes it suitable 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).

  • Considering its dry weight of 352 pounds, the Westinghouse WGen12000 is one of the heavier generators producing between 10000 and 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.
  • At a lowest noise rating of 74 dBA, this generator is one of the quieter devices 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.
  • 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 autonomy is your priority, one of the devices of a similar power output with the highest run time is the Powerhorse 13000ES, reaching around 15 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. 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.
