Westinghouse WPro12000 is an industrial portable generator designed for residential, recreational and industrial use. The robust WPro12000 can be moved easily from the house to the job site or a recreational site. Circuit breakers and low-oil shutoff protects the unit for user safety. It serves as an ideal choice for construction sites, picnics and patio parties. Sound attenuation features, heavy-duty performance, low THD, and low cost makes it a preferable choice for those looking for reliable standby portable power.

This Westinghouse portable generator offers clean power and is safe for electronics that have sensitive electrical components. It can also be used as a backup supply of power when grid power fails. Westinghouse WPro12000 is transfer switch ready. The transfer switch can isolate selected circuits of your home from the power lines and allows you to use the unit with two sources of power. It also prevents back-feed, which occurs when the power goes back down the utility lines.

The 22 HP 713cc V-Twin Engine features low idle control that helps control the speed of the engine. It is pressure-lubricated and has heavy-duty features for industrial use. The cast iron sleeve makes it a very durable option.

It generates 12,000 running watts and 15,000 peak watts, which are ample to run an AC; a sump pump, an electric stove, coffee maker, microwave, dishwasher, and other household appliances. It has two 5V USB ports for charging electronics with microprocessors such as phones and tablets.

At the job site, you can use it for an AC, dust controllers, air compressors, electric saws and running all sorts of electric tools. OSHA requires GFCI protection for job-site power sources and this unit has just that.

Westinghouse WPro12000 runs for 16-hours on 10.5 gallons of fuel on a 25% load. This generator offers good value for your money. The price is very affordable while financing options are available for those who are on a tight budget.

All 120V and 240V outlets have rubber covers for added safety. The professional grade WPro12000 comes with a battery, battery charger, key fob, oil, funnel, tool kit, manual and quick start guide. Along with the residential and commercial warranties buyers also get lifetime technical support.
