The present disclosure relates to the field of electrical engineering and discloses an assembly (100) for facilitating safe electrical connection between a circuit breaker (10) and a plurality of electrical connectors (20) inside an electrical panel board (30). The assembly comprises a plurality of connecting members (102) and a support block (104). Each connecting member (102) has a first connecting end (102a) connected to the terminals (10c) of the circuit breaker (10) and a second connecting end (102b) connected to the electrical connectors (20). The support block (104) comprises a plurality of projecting surfaces (104a), slots (104b) defined between the projecting surfaces (104a), and elongated members (104c). The slots (104b) provide a rigid support to the electrical connectors (20) to prevent bending and rotation of the connectors (20) on being subjected to a high torque. The elongated members (104c) isolate the connecting members (102) from each other.

An intermediate disconnect section (100) for mounting on a meter base (10) and an electricity meter (20). A first source coupling (117) mounted on a platform (106) is electrically couplable to a source connector of the meter base (10). A second source coupling (119) is electrically coupled to a source connection of the electricity meter (120). A first load coupling (121) is electrically coupled to a load connector of the meter base (10). A second load coupling (123) electrically coupled to a load connection of the electricity meter (20) and to the first load coupling (121). A switch (110) couples and decouples the first source coupling (117) to and from the second source coupling (119). A switching mechanism (130) opens and closes the switch (110) and includes an external device (138) that allows a user to open and close the switch (110) manually.

The present invention relates to the field of electrical installations, and in particular to the automation of the manufacturing of electrical panels adapted to their environment. The components of the electrical panels of the invention are organised in separated boxes depending on whether they are supplied with high power or low power. The components are selected and organised according to their function and the family of equipment that they manage or power, in an identifiable way. This simplifies the maintenance work of the panel, and can be safely carried out even by an unqualified operator.

Embodiments provided herein are directed to an improved way to access and increase the area of an electrical distribution device provided for cable pulling and cabling. A rotatable section, on which several electrical components of the electrical distribution device are attached, can be rotated away from the cabling area as a single unit. This permits easier access to the cabling area and increases the size of the cabling area, which results in less time required to pull cables and wire the electrical components of the electrical distribution device.

An electrical device includes a fixed support with supply lines and a distribution circuit to supply power to a contactor block. Each contactor block includes secondary lines, each connected to a supply line, and is movable between joined and disjoined positions. Each contactor block includes a switching device for switching all secondary lines of the contactor block between open and closed. The electrical device also includes a control block, movable between joined and disjoined positions. When in the joined position, each contactor block also is held in the joined position, an electronic monitoring device of the control block also being connected to the switching device of each contactor block to control switching of each switching device independently. When the control block is in the disjoined position, the switching device of each contactor block opens the secondary lines, while each contactor block is movable between its joined and disjoined positions.

A switchgear system includes a switchgear frame and a truck carrying a circuit breaker, which includes a breaker housing, a fixed electrical contact and a movable electrical contact mounted within the breaker housing, an actuator piston connected to the movable electrical contact, and a drive assembly coupled to the actuator piston. A sensor circuit is mounted on the switchgear frame under the truck and aligned with the circuit breaker and configured to acquire displacement data of the actuator piston when in a contact testing position. A controller is coupled to the sensor circuit and configured to receive the displacement data and determine electrical contact erosion within the circuit breaker.
