The present disclosure provides an electrical power supply structure comprising a plurality of insulated pipes, each insulated pipe extending longitudinally and configured to carry high amperage electrical power, a barrier support plate comprising one or more openings for receiving the plurality of insulated pipes, the barrier support plate configured for mounting over a hole through a floor of a building, a first support structure extending longitudinally upward from an upper side of the barrier support plate, and a second support structure extending longitudinally downward from a lower side of the barrier support plate through the hole. Each of the first and second support structures comprises a longitudinally extending enclosure having a plurality of transversely extending conductor support members for supporting the plurality of insulated pipes, and the plurality of insulated pipes are grouped by phase.

A submersible control system with a control panel. The control panel has a frame to house electronic components. The frame has a connection opening for wiring required for an electrical connection to the electrical components. An outer door is attached to the frame to be water-tight to the frame in a closed position thereof. A conduit is sealed to be water-tight with respect to the connection opening. The conduit is filled with an epoxy for water-tight sealing an interior of the conduit to the wiring fed through the conduit. The control panel will remain water-tight for at least 24 hours after being submerged.

A switch cabinet with at least one brush strip for the conductor feed-through, the switch cabinet having a switch cabinet frame with a horizontal or vertical profile frame from which a profile web extends, wherein the brush strip is placed on a free end of the profile web with bristles extending from the profile web over the inner portion of the profile frame.

A method of making a forming wheel includes mixing and melting an electrically conductive material, a latex rubber material, and a polycarbonate material to produce a weatherproof material mixture, blending carbon black with polyethylene to produce an electrically conductive additive, positioning an injection mold of the forming wheel in fluid communication with an exit end of a heating barrel, injecting the weatherproof material mixture into an entry end of the heating barrel, introducing the electrically conductive additive through a lateral port of the heating barrel proximate to the exit end to partially mix with the weatherproof material mixture to produce an injection mixture, and injecting the injection mixture into the injection mold to produce the forming wheel.

Current transformer (CT) retainers (100, 200, 300, 400) are disclosed for use in an electrical enclosure (510) for an electrical panel (500). An exemplary CT retainer includes a body that has one end portion (110, 210, 410) configured to mount onto a wall (140) of the electrical enclosure. The body of the CT retainer also includes an opposite end portion with a basket (150, 250, 350, 450) for housing a CT. The basket includes a flexible clip (160 and 180, 260 and 280, 360 and 380, or 470) which is configured to flex to allow insertion of the CT into the basket or removal of the CT from the basket.

An electric connection box includes a frame, a lower cover that covers the lower surface of the frame, and at least one block that is attached in the frame and disposed at a position along a peripheral wall of the frame. An electric wire that is connected to a component attached to the block out of the blocks is drawn horizontally from the block toward inside the frame.

An insulating block configured for attachment to an electrical structure without the use of a tool. The insulating block is formed from an electrical insulator. One of the electrical structure and the insulating block may have a clip that is configured to engage a catch surface on the other of the electrical structure and the insulating block without the use of a tool. An opening or recess of the electrical structure may be configured to receive a portion of the insulating block having the clip or catch surface, and the portion of the insulating block may move within the opening or recess from a disengaged position to an engaged position, in which the clip engages the catch surface to securely attach the insulating block to the electrical structure. The electrical structure may be a meter socket enclosure. The combination of the insulating block with the electrical structure.

A cable feedthrough for a control cabinet having a casing that can be closed with a casing cover. The cable feedthrough includes a frame which is open on one side and can be fastened detachably to and flush with an end face of the casing. At least one removable feed element for feeding through a cable is situated in the frame.

A PDU enclosure defines a transformer compartment for receiving a transformer. The PDU enclosure includes a first side bulkhead and a second side bulkhead positioned adjacent to each other as viewed on a plane. The first side bulkhead and the second side bulkhead limit access to the transformer compartment from the front. The first side bulkhead defines an opening to the transformer compartment and is spaced from the second side bulkhead by a gap. The PDU enclosure further includes a removable access panel. The removable access panel includes a first portion removably coupled to the first side bulkhead and that covers the opening in the first side bulkhead, and a second portion extending at an angle relative to the first portion and removably coupled to the second side bulkhead. The second portion also covers the gap between the first side bulkhead and the second side bulkhead.

The invention relates to a switch cabinet with at least one brush strip for the conductor feed-through, the switch cabinet having a switch cabinet frame with a horizontal or vertical profile frame from which a profile web extends, wherein the brush strip is placed on a free end of the profile web with bristles extending from the profile web over the inner circumference of the profile frame.
