    Summary

    The Westinghouse WGen5300sc is a gasoline generator built around 5300 running watts and 6600 starting watts. That combination gives it steady output for ongoing loads while also providing extra headroom for equipment that needs a stronger surge to get moving.

    Because it runs on gasoline, the WGen5300sc pairs its wattage with a familiar fuel choice for many users who want straightforward refueling and a conventional generator setup.

    Power & Runtime

    With 5300 running watts and 6600 starting watts, the WGen5300sc is designed to handle continuous demand while still accommodating higher start-up draw when motors or compressors kick on. Its noise level is rated at 68 dBA, which sets expectations for audible operation when it is running under load.

    Runtime is clearly defined at two load points: 14.5 hours at 25 percent load and 11 hours at 50 percent load, giving you a concrete sense of how long it can stay in service between refueling stops. Total harmonic distortion is listed at 23 percent, a figure that helps frame the character of the power it produces for connected devices.

    Portability

    At 133.8 lbs, the WGen5300sc is a substantial unit, and its physical presence is reinforced by its 23.2 x 20.1 x 19.1 inch dimensions. Those measurements help you visualize the footprint it will take up in storage or in a working area, while the weight signals that moving it is a deliberate task rather than a grab-and-go lift.

    Features

    Westinghouse equips the WGen5300sc with both recoil and electric starting, letting you choose between a manual pull start and push-button convenience. A built-in fuel gauge supports easier planning by giving you a direct read on fuel status during operation.

    For use cases that call for regulatory alignment, it lists CARB and EPA compliance. It is also RV ready, which simplifies pairing it with RV power needs, and it includes a spark arrestor for added safety considerations. Covered outlets add a layer of protection for the connection points, while AVR automatic voltage regulation is included to manage voltage output during changing loads. The package is backed by a 3-year warranty.

    Recommended Audiences

    • RV owners needing RV-ready power
    • Shoppers who prefer gasoline-powered generators
    • Homeowners needing whole-house or jobsite backup power
    • Users who value push-button or remote start convenience

    These are estimates using typical wattage assumptions. Real appliances vary. Startup surges can be 2–6× the running wattage for motor-driven loads. 240V loads require a 120/240V generator and proper connection. Use a transfer switch or interlock kit; never backfeed a panel.
