A safety device for medium-high voltage system is disclosed and includes a cabinet, a power module and a metal cover plate. The cabinet includes an accommodation seat connected to the medium-voltage charged region and having an opening. The power module is detachably disposed in the accommodation seat through the opening. The metal cover plate is pivotally connected to the accommodation seat and grounded. When the metal cover plate is in the first position, the opening is closed and the medium-voltage charged region is shielded. When the power module is set in the accommodation seat, the metal cover plate is pivotally rotated to a second position, and the power module is electrically connected to the medium-voltage charged region. When the power module is detached from the accommodation seat, the metal cover plate is rotated to the first position, and the opening is closed to shield the medium-voltage charged region.

An electrical/electronics power distribution cabinet is disclosed which includes internal components enabling the cabinet to be quickly and easily reconfigured for allowing all cabling to exit an upper end of the cabinet or a lower end of the cabinet. The cabinet includes fully isolated top and bottom panelboard circuit breaker areas and a movable internal wall portion that helps to form an isolated compartment to route electrical cabling within the interior area of the cabinet, while keeping the cabling associated with the two panelboard circuit breaker areas fully separate from one another. This enables access to one of the top or bottom panelboard circuit breaker areas for service or reconfiguration without the need to access the other.

An interlocking external actuator for accessing an electrical panel board having a circuit breaker inside a housing that is covered by an enclosure door, wherein the actuator includes a handle, a first shaft, a second shaft and an interlocking mechanism, wherein the second shaft engages the first shaft in a closed state of the door and thereby facilitates switching the circuit breaker to ON and OFF states by angularly displacing the handle, wherein the interlocking mechanism is biased to engage in pushing the door into a closed state, wherein the circuit breaker is switched from an ON state to an OFF state by displacing the handle from a first angular position to a second angular position, and wherein the interlocking mechanism is disengaged through displacement of the handle further to a third angular position and thereby allow opening of the door.

An energized parts guard is disclosed comprising a panel of substantially rigid, electrically insulative material wherein the substantially rigid panel further comprises a first one or more apertures and a second one or more apertures. The first one or more apertures are so dimensioned to accept one or more circuit breakers inserted into the first one or more apertures such that there is less than a 12.5 mm gap between the panel and the circuit breaker on at least two sides of the one or more circuit breakers. The second one or more apertures are positioned to facilitate access to at least one terminal of each of the one or more circuit breakers when the one or more circuit breakers are inserted into the first one or more apertures.
