Abstract
The invention relates to a method and system for secure confirmation of the status of a metering disconnect switch. By utilizing both a mechanical auxiliary switch and the reading of a load-side voltage immediately after a switch operation, a nearly certain decision can be achieved that the state of the relay is accurately known. This invention will prevent a motorized or solenoid driven switch operator from achieving a close or open state of the switch that otherwise could be uncertain.
