| 188 | "SAVUS" A simple, low cost emergency home power connection | US15829679 | 2017-12-01 | US20180174790A1 | 2018-06-21 | Gordon Young |
| There is a need in homes and small businesses for simple devices to help residents in emergency situations. Extended power outages are an example. “SAVUS” is a simple, safe, low cost device to connect emergency power to an entire home. Current emergency power solutions are costly and usually require complex installation. SAVUS has models which install into most residential type circuit breaker front panels and require only one available circuit breaker space for installation. SAVUS mechanically interlocks with the main circuit breaker and will not allow connection of an external power source to the circuit breaker box until utility power is turned off for safety. Because it is on the house side of the main circuit breaker and completely enclosed with other circuit breakers, utility approval is not normally required. We believe SAVUS may become nearly as common in homes as smoke detectors. | ||||||
