NEMA AUTO-SWITCHING DUPLEX MODULE

摘要

A system and method, i.e., a utility (50) for providing power to an electrically powered device from alternate, redundant power sources via a single power cord. The utility (50) is operable to provide redundant power to an electrical device having a power cord terminating in a standard plug. The utility (50) is operable to sense an interruption of power from one power source, and to switch a connection to another power source in response to the interruption. The housing (52) of the utility (50) may be configured to match the form factor of a standard (e.g., NEMA or other electrical standard) duplex receptacle unit. The utility may be incorporated into a standard outlet box or may plug into a standard outlet box.
