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.

An apparatus includes an enclosure, a power switch, a cable actuator, a power converter and a manual switch. The enclosure may be mechanically attachable to an external side of an industrial control panel. The power switch may be configured to switch electrical power. The cable actuator may be configured to control the power switch and may have an end connectable to a power disconnect handle of the industrial control panel. The power switch may be open while the power disconnect handle is in an off position and closed while the power disconnect handle is in an on position. The power converter may be configured to generate low-voltage power from the electrical power. The manual switch may be configured to switch the electrical power from a load side of the power switch to the power converter. A wire may transfer the low-voltage power through at least one aperture.

An apparatus includes an enclosure, a power switch, one or more power converters and a wire. The enclosure may include a door. The power switch may be mounted inside the enclosure and configured to switch electrical power from a line-side power line to a load-side power line. The load-side power line may be configured to transfer the electrical power outside of the enclosure to an industrial control panel. The one or more power converters may be configured to generate a low-voltage electrical power from the electrical power. The wire may be configured to transfer the low-voltage electrical power outside of the enclosure.

The arrangement includes a pressure relief hatch for closing an opening in a wall in an electric cabinet, which. includes a body having an outer surface, an opposite inner surface, an outer perimeter, and a thickness. The body includes a centre portion with a first thickness, an intermediate portion with a second thickness, and an outer portion with a third thickness. The first thickness is greater than the third thickness and the second thickness decreases in a radially outward direction from the first thickness to the third thickness. A spring keeps the pressure relief hatch in a closed position in the opening during normal operation of the electric cabinet.

Disclosed is a panel board including a panel for automatically adjusting a humidity of an interior thereof, the panel board including an outer wall panel manufactured in a specific standard and a roof panel coupled to an upper side of the outer wall panel to define a roof thereof, and having a space part, in which various pieces of electric power equipment are installed, on the inner side thereof, wherein an interior and an exterior of a wall of the panel board are coated such that moisture absorption capacities of the interior and the exterior of the wall are different.

A kit includes one or more pairs of matching color-coded attachment members and tags. The attachment member is configured to be selectively retained to an electrical wire entering an electrical service panel. The corresponding color-coded tag is configured to be attached, such as through magnetic means, to a door of the electrical service panel. The tag includes pre-printed text thereon, which provides descriptive information regarding the electrical circuit formed by the wire to which the attachment member is associated. As such, the color-coding allows a homeowner or technician to easily identify which electrical circuit is controlled by a particular electrical circuit breaker.

A system and leveling device for installing an electrical box or ring on a wall stud, and a process for installation using the same. The leveling device has a generally planar elongated substrate having a horizontal bubble level on a front face and positioning pins on a rear face. The positioning pins are configured for insertion into gang screw holes on the electrical box or ring. The system includes cross-stud braces for spanning the distance between adjacent wall studs. The electrical box or ring has pass-through slots to receive the cross-stud braces so that the electrical box or ring can be leveled using the leveling device prior to attaching the cross-stud braces to the wall studs.

Embodiments of the presently disclosed invention may enable electrical components and connections to be monitored within electrical distribution equipment cabinets having a blanking panel. Such an IR/UV-permitting panel may replace the pre-existing blanking panel in order to monitor the adjacent area having the targeted components and connections to be monitored. NFC tags may be utilized in connection with an IR/UV-permitting panel to enable data acquisition and management systems for the monitoring of electrical components in a cabinet.

An electrical cabinet includes a cabinet frame, two or more hoist brackets, a hoist bar, and a hoist mechanism. The cabinet frame has a top section and a bottom section. The bottom section rests on an underlying supporting surface, and the top section is positioned at an opposing side of the cabinet frame from the bottom section. The hoist brackets are coupled to the top section of the cabinet frame. Each of the hoist brackets has a respective indentation. The hoist bar rests in the indentations of the two or more hoist brackets, and includes a first groove. The hoist mechanism rests in the first groove of the hoist bar. The hoist mechanism is configured to facilitate lifting and positioning of an electrical component of a power distribution system within the electrical cabinet. The electrical component can be a bus assembly for a switchboard.

The invention relates to a switch cabinet having a frame and a sidewall element mounted thereon, wherein the sidewall element is mounted on the frame via at least one latch lock, the latch lock having a latch and a latch receptacle one of which is fixed to the frame and the other of which is fixed to the sidewall element and which are accommodated in a volume which is open towards an outer side of the frame and which is delimited on the one hand by a folded profile edge of the frame and on the other hand, adjoining the folded profile edge on the outer side, by the sidewall element.
