Abstract
This invention creates a simple, low cost mechanical transfer switch (called Gen/Safe) which provides users the ability to connect nearly any portable household generator to supply whole house power (to the limit of the particular generator) in the event of an emergency outage. Installed by the utility in less than five minutes, the switch provides visual confirmation of utility isolation while still allowing user supplied power not only from emergency sources, but also allows PV, wind, and other on-site power to operate normally to supply the home directly without interruption when possible. This connection is also suitable as an ongoing utility connection for user generated alternate energy power systems while providing an additional utility safety isolation factor for alternate power sources which must shut down when utility power fails; (to protect repair personnel).
