A latch device is provided for an electrical enclosure. The latch device includes a latch plate which is movable between extended and retracted positions. In the extended position, the latch plate allows a door to be secured over an opening in the enclosure. In the retracted position, the latch plate permits unencumbered access to components and mounting structures within the enclosure, such as for removal of a mounting unit. The latching mechanism may bias the enclosure door to a closed position, while permitting movement of the door, without unlatching of the mechanism, during fault conditions within the enclosure, such as to permit the escape of hot gasses.

Arc resistant electrical enclosure system and method

A technique is provided for applying secondary or backup power to a networked device in the event of a loss or malfunction of network power. In a control and monitoring network. Various devices may receive both power and data signals from a network cable. In the event of loss of network power, or the reduction in network power, the devices can automatically and without interruptions seek power from the secondary power source.

Backup power module for industrial control and monitoring network

A network is configured to apply power and data signals to networked devices for operation of the devices. A backup power supply module is coupled to the source of network power and to a secondary power source. The secondary power source may have an adjustable voltage level or a level fixed with relation to the network power voltage level. In the event of a loss or insufficiency of network power, power from the secondary source is automatically applied to the connected device or devices. The device may be programmed for certain failure modes and the secondary power source provides the power needed for operation in the event of loss of network power.

Method and network for providing backup power to networked devices

A motor control system comprising a plurality of motor controllers and a power source adapted to drive an electric motor. The motor control system comprises a switch that is selectively operable between at least a first position and a second position. In the first position, the power source is coupled to a first controller to provide the power to drive the electric motor. In the second position, the power source is coupled to a second controller to provide the power to drive the electric motor. The switch also electrically isolates the input and the output of the first controller from the power source when the manual bypass switch is positioned in the second position.

System and method for bypassing a motor drive

In one embodiment, the components within each respective unit of the MCC are connected powered by a connector assembly that is directly engaged to secondary power and network data conductors disposed of within the enclosure. The connector assembly, if so desired, will maintain connection even upon disengagement of the unit from the main power supply. This service position can be employed to provide a safe environment for diagnostic testing and repair of the unit. In another embodiment, the secondary power and network data conductors may by carried over an open rail system. This embodiment provides a convenient means of quickly and easily engaging the secondary power and network data conductors to the unit. Another embodiment provides a method for placing the unit into a service position.

Motor control center interconnection method and apparatus

A system operable to detect voltages within an electrical device and provide an output based on the voltages detected by the system. The electrical device may include an isolation switch adapted to selectively isolate the electrical device from an electrical bus. The system may be operable to detect voltage data in the electrical bus and the electrical device downstream of the isolation switch. The system may provide an indication that voltage is detected in the electrical bus, but that no hazardous voltages are detected within the electrical device downstream of the isolation switch. The system may be adapted to produce a plurality of outputs based on the voltage data detected on the electrical bus and in the electrical device downstream of the isolation switch.

Method and system for verifying voltage in an electrical system

A connector system is provided in which a branch connector may be secured in a pre-wired power and data network. The branch connector is designed to interface with existing network connections to provide at least one additional interface point for added or temporary devices. The connector may be designed to interface with existing connectors in a manner similar to existing cable assemblies, and may present sockets or similar interfaces which are substantially identical to the interface to which the connector is applied. Expanded network connectivity is thus provided for additional devices or temporary devices, such as programming, logging, system configuration and troubleshooting, and similar applications.
