Provided in this disclosure is a reversible power supply enclosure. A base component defines a body of the power supply enclosure. The base component includes a base surface and side surfaces formed along opposing edges of the base surface. An offset flange is formed along the base surface. A closed end component is connected to the base component and includes a second offset flange. The offset flanges displace the base component the predetermined distance from the mounting surface. A cover component includes a primary surface and a perpendicular secondary surface for enclosing the base component. A lip portion substantially surrounds the peripheries of the primary and secondary surfaces, thereby enabling the power supply enclosure to be reversibly mounted in either a vertical orientation or a horizontal orientation such that both orientations provide a moisture-resistant power supply enclosure.

A locking system for an enclosure, including a control bracket mounted to a door of the enclosure and configured to slide in a longitudinal direction along a guide rod running through a pin bracket of the control bracket. The control bracket further includes a latching pin to secure the door of the enclosure. A handle mechanism has a push rod that causes the control bracket to slide along the longitudinal direction, also causing the latching pin to move into a position that secures the door.

An apparatus for retracting and extending a main body of a circuit breaker includes: a conveying module for retracting or extending the main body into or from a distribution box of the circuit breaker; a lever module including a lever selectively switching between a first state and a second state, where the lever module allows movement of the conveying module when the lever is in the first state, and disallows movement of the conveying module when the lever is in the second state; and an interlock module configured to allow the lever to switch to the first state only when a predetermined external input is applied to the interlock module.

A motor control center includes an enclosure comprising an isolation switch, a main contactor device, and a ground switch device. The isolation switch is selectively manually operable between a connected state and a disconnected state. In the connected state the isolation switch is adapted to conduct electrical power from an associated power source to the main contactor device and wherein the isolation switch in the disconnected state interrupts conduction of electrical power from the associated power source to the main contactor device. The main contactor device is selectively operable between a conductive state and a non-conductive state, wherein the main contactor device is adapted to electrically connect the isolation switch to the ground switch device and to an associated electrical load when the main contactor device is in its conductive state and wherein the main contactor device disconnects said isolation switch from the ground switch device and the associated electrical load when the main contactor device is in its non-conductive state. The ground switch device is manually operable from an open, ungrounded state in which the main contactor device is electrically disconnected from a ground path to a closed, grounded state in which the main contactor device is electrically connected to the ground path. The motor control center further includes a first interlock device operably connected between the isolation switch and the ground switch device, wherein the first interlock device prevents movement of the isolation switch from the disconnected state to the connected state when the ground switch device is in the grounded state.

A modular electrical-cabinet mounting apparatus (110) is provided comprising a base wall assembly (122) defining a cabling void (124) and a multi-part support platform (126) which is mountable to the base wall assembly (122) to at least partly cover the cabling void (124). The support platform (126) comprises a plurality of individual platform members (132a, 132b, 140) which are interconnectable to form the support platform (126). At least two said platform members are formed as cabinet-support members (132a, 132b) having a cabling access aperture therethrough and the support platform (126) is configured to be selectively assembled so that the cabinet-support members (132a, 132b) are in a spaced-apart relationship along the length of the support platform (126).

The invention is directed towards a modular energy storage system for receiving power from a source, storing energy within a storage module, and delivering power to a load. The system includes a master unit containing the storage module for storing energy, and an inverter for receiving AC power and converting to DC power for storage. The system may also include at least one slave unit containing additional storage modules to increase energy storage capacity.

A cable inlet device consists substantially of an open frame part and at least one sealing insert arranged therein. This cable inlet device is attached to a switchgear cabinet so that the sealing insert and the frame part of said cable inlet device terminate flush with said opening. When the switchgear cabinet is closed, for example by a switchgear cabinet door or switchgear cabinet wall or the like, this door or wall is sealingly pressed with a counterpart seal against the cable inlet device. For replacement of cables it is merely necessary for the switchgear cabinet door/switchgear cabinet wall to be opened and for the cable to be changed to be removed together with the corresponding sealing element, and for the new cable to be provided with a matching sealing element and to be inserted.
