A Generator for Home Backup (Winco PSS8B): LP/NG 1-Phase

…Uses Natural Gas(NG) or Liquid Propane(LP)

This standby generator is best suited for: 1)small to medium-sized homes (recommended for applications 1500 - 2000 square feet); 2)small or home-based businesses (that use standard single-phase 120/240-volt electricity).

This Winco PSS8B is a generator perfect for home backup, or the backup of small or home-based businesses; in a typical residential application with single-phase 120/240-volt power, the Winco PSS8B4W can run basic lights and outlets in an area of roughly 2500 square feet (leaving no excess capacity to run appliances). We believe that a generator of this size can provide good mixture of lighting and appliances-operation in a home 1500 - 2000 square feet in size. A generator with 8 kW should operate a 2-ton central-air unit, or a swamp cooler. Central heat is unlikely. Should also run major appliances, depending on their starting watts, from one to five at a time. A generator such as this model will not afford whole-house backup, so you will have to pick and choose what circuits and appliances are being run together. Must also be connected to a transfer switch for safe operation (see Switch Options tab for list of appropriate models). Model shown has 4-wire start. PSS8B2W 2-wire start model also available - call for details. This is a generator
with CARB certification, available to California residents.

  • Shipping

    The T-REX Free Shipping Pledge:
    The manufacturers we work with are large concerns that ship multiple items each day. This enables them to attain the best shipping rates available. T-REX passes these savings on to our customers by providing free shipping to any commercial or residential address in the continental United States. This is the T-REX pledge. We will adhere to it even when a freight carrier adds one-time or unanticipated shipping fees. Try obtaining these terms from another Internet-based generator seller. You will not find a more customer-friendly policy than ours.

    About Lift Gates:
    Typical delivery trucks are designed to be unloaded at docks, or by forklifts. In other words, they are designed to deliver to commercial locations where such options are available. By contrast, a lift gate-equipped truck lowers heavy items from the truck trailer (which can be several feet high) to the ground, using a hydraulic mechanism similar to an elevator. If your delivery will go to an address not equipped with a loading dock, and you don't have access to a forklift, then selecting the lift-gate delivery option is a convenient alternative.

    A generator from T-REX can weigh hundreds of pounds. Without access to a loading dock or forklift, unloading one safely may require several able-bodied individuals. Delivery drivers are NOT required by their companies to help customers unload. Unless you are certain that a sufficient number of helpers will be available during the delivery, we urge you to specify the lift-gate shipping option before checking out. Charge for the lift-gate is $75.00, and is NOT included in the Free-Shipping Pledge offered by T-REX. We feel, however, that it is worth the investment.

    Residential Delivery:
    You need to inform us if your delivery will be going to a residential address. Freight companies need to know this because many residential areas can't be serviced by large semi trucks. The generator will instead be loaded onto a smaller truck tailored to home deliveries. A home which serves as a place of business (regardless of the presence of company name/signage), if located in a residential area, is still considered a residential address for shipping purposes. Please select the residential delivery option if applicable. T-REX agrees to pay all additional residential delivery costs, but to do so, we must be properly informed before shipping arrangements are made.

    To select your choice of residential or commercial delivery, please see the purchase options in the Add To Cart area.
