Abstract
A connector and connection arrangement for connecting an alternative power supply to a user incoming electrical power center, commonly referred to as the load center or breaker panel, when power from a utility power source is not being received. The connection includes an individual housing for the connection to the alternative supply or the connection may be located in a common housing which houses both the connector and the utility meter. The alternative supply is connected to the load connected and load feeding side of the meter socket and is electrically positioned in front of the load circuit breaker panel which normally includes the individual service disconnects. The connection includes at least one and preferably a pair of open-center switches and a sensing circuit therefore to sense receipt or termination of utility power delivery to the user to actuate such switches and open the utility supply switch and close the switch to the alternative source only after two indications of power supply stoppage are determined. When utility power is restored, the alterative source is disconnected and the utility power is reconnected.
