A support rail and housing assembly is mountable on a housing base. The housings are equipped with electrical contact and/or functional elements which can be strung together. The support rail is mountable on the mounting base even when the housings have already been arranged on the support rail before the support rail is mounted. The support rail is secured to the mounting base by two or more mounting pins which have been placed before the support rail is mounted to the mounting base. The mounting pins and the support rail are designed to correspond to each other such that the support rail can be placed on the mounting pins and locked thereto without using a tool.

The present invention relates to a contact device for transmitting electrical energy from a possibly movable, but preferably spatially fixed, bus bar to a tap-off device which may be movable along the bus bar or may be likewise spatially fixed. For this purpose, the sliding contact elements are configured in the form of sliding clip elements so that the connecting housing of the contact device is clippable onto the bus bar without using tools.

A high voltage electric switchboard in which manufacturing productivity is greatly improved and each functional part can be easily replaced and repaired is provided. In the high voltage electric switchboard, a plurality of functional parts including a bus bar part, a measurement and supervisory controller, a circuit breaker part, a wire part, and potential transformer part are independently modularized such that the functional parts do not have a shared surface with each other and at least two outer surfaces of an enclosure of each of the modularized functional parts are installed to be in contact with an outer surface of an enclosure of another functional part adjacent in a horizontal direction or a vertical direction.

Embodiments of the present disclosure provide a panel-type electrical device. The panel-type electrical device comprises a socket assembly adapted to be coupled to a mounting surface and including a socket body and a first pair of mounting parts; a switch assembly adapted to be coupled to the mounting surface side by side with the socket assembly and including a switch body and a second pair of mounting parts, each of the mounting parts including a first surface facing toward the mounting surface and a second surface facing away from the mounting surface; a socket panel adapted to cover the socket body; a switch panel adapted to cover the switch body and move between at least two positions to control an operation state of the switch body, the switch panel being coplanar with the socket panel in one of the at least two positions; and a first pair of cushion blocks adapted to be arranged between the mounting surface and the first surface of the corresponding mounting parts of the socket assembly such that the socket body abuts the switch panel.

An electrical panel adapter for an enclosure that is formed of at least one panel includes a main unit having a front portion and a rear portion. The rear portion is positioned inside the enclosure and includes a first plurality of electrical connections adapted to connect to electrical wires and/or equipment located inside the enclosure. The front portion extends through an aperture in the at least one panel and includes a second plurality of electrical connections adapted to connect to one or more electrical devices located outside the enclosure for measurement of both voltage and current inside the enclosure. The second plurality of electrical connections are electrically coupled to the first plurality of electrical connections. The electrical panel adapter enables electrical devices outside the enclosure to be electrically coupled to the electrical wires and/or equipment inside the enclosure without requiring the enclosure to be opened.

Prefabricated electrical modules and system along with fabrication and construction methods are provided. The prefabricated electrical system includes multiple framed, prefabricated electrical modules of one or more types. The prefabricated electrical module disclosed may comprise one or more of a main service electrical module, a low-voltage module, a switch component module, and a receptacle component module. The casing of the interior components of the modules is weatherproofed and/or weatherized. Each of the modules includes a module exterior frame that accommodates the specialized elements of that particular module. Methods for fabrication of the modules are disclosed. Construction methods for installing the assemblies are also disclosed.

The present invention relates to a contact device for transmitting electrical energy from a preferably spatially fixed bus bar to a tap-off device which is movable along the bus bar or is likewise spatially fixed. For this purpose, the sliding contact elements are configured in the form of sliding clip elements so that the connecting housing of the contact device is clippable onto the bus bar without using tools.
