Medical-device power supplies vary; default is only a planning estimate and users should follow clinician/manufacturer guidance.
Never operate a fuel-burning generator indoors, in a garage, on a porch, or near open windows. Use a listed transfer switch or interlock installed by a qualified electrician for home wiring, and verify actual device nameplates before buying equipment.
Medical-device backup should be reviewed with the device manufacturer, clinician, or power supplier. This calculator is only a planning estimate.
