  • Electrical power distribution control system with dual voltage sources
    Patent number: 6320732
    Abstract: The present invention provides a power distribution system with a split section panelboard that provides two interior sections. Each section is supplied power from a separate power source. A common bus bridges the two sections. Remotely-operated circuit breakers for both the sections are connected to the common bus. A power interface unit converts power from one of the power sources to provide low voltage power for the circuit breaker motors and a control unit. The control unit in the panelboard controls the operation of the circuit breakers of both the sections.
