An electrical panel board includes an enclosure defining a first and second chamber, a power distribution module disposed in one of the first chamber and the second chamber and adapted to electrically connect a main power source to receive power thereof with one or more loads. A neutral assembly is positioned in the remaining of the first chamber and the second chamber and securable to the rear wall of the enclosure. The neutral assembly includes a neutral circuit and a ground fault protection unit electrically coupled to each other. The neutral assembly having the neutral circuit and the ground fault protection unit extends from the rear wall to an imaginary plane which is off set rearwardly from an imaginary plane along which the power distribution module extends from the rear wall.

A switchboard is provided having a rotating shutter structure that comprises: a switchboard body that is provided with a circuit breaker chamber into which a circuit breaker is inserted, and an open hole formed in the rear surface to expose a conductor part of a bushing assembly to the circuit breaker chamber; a shutter part that is rotatably installed in the switchboard body and opens/closes the open hole by rotating; and an operation unit that is installed in the switchboard body and rotates the shutter part when the circuit breaker is inserted into the circuit breaker chamber.

Disclosed herein is a panelboard guard assembly configured to restrict access to a panelboard having a cover and a door defined therein, the cover having first and second side edges. The panelboard guard assembly includes overlapping members that are, at least in some implementations, mutually coupled to each other. The panelboard guard assembly further includes an adjustment mechanism that extends between and couples the members together, the adjustment mechanism facilitating adjustment of the distance between the outer ends of the members.

An arc shield for electrical switching apparatuses is provided. The arc shield comprises a mounting base and a detachable barrier and includes a multi-point mounting system that eliminates the need for hardware and gloves when installing the detachable barrier on the mounting base. The mounting base is formed with a hinge tab and two locking tabs, and the detachable barrier is formed with a corresponding notch and two tab receiving openings formed with retention profile. The notch can be seated on the hinge tab in order to establish a hinge, and once the hinge is established, the locking tabs can be inserted through the tab receiving openings by bending the detachable barrier. Once the bending force is removed, the retention profiles of the locking tabs ensure that the detachable barrier cannot be removed from the mounting base unless a bending force is intentionally reapplied to the barrier.

The invention relates to a control and/or switch cabinet (100) for a machine at least partially operated by electric power, for example a packaging machine. Said cabinet comprises a frame, at least one front door, and a main switch device including a main switch unit transferable between a power on position and a power off position, a manually operable main switch operating unit operatively connected to the main switch unit for transferring the main switch unit between the power on position and the power off position, said main switch operating unit being located at the front side of the cabinet, and an exclusively mechanically operating front door safety ensuring unit allowing opening the at least one front door only if the main switch unit is in its power off position and allowing transferring the main switch unit to its power on position only if the at least one front door is closed. According to the invention, the main switch operating unit is mounted on the front door panel.

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.

A filler plate for a loadcenter having an opening in a deadfront includes a cover plate constructed to cover the opening; a first leg coupled to and spaced apart from the cover plate to yield a first gap between the first leg and the cover plate, wherein the first gap is constructed to receive a first portion of the deadfront adjacent to the opening therein; and a second leg coupled to and spaced apart from the cover plate to yield a second gap between the second leg and the cover plate, wherein the second gap is constructed to receive a second portion of the deadfront adjacent to the opening therein.
