A kit or system, which can be used for automated assembling and/or disassembling of laminated electric circuits can be comprised of insulating sheets, line conductors between insulating layers, which may have insulated spacers for structural straightening. Dedicated electric elements can be connected to the structure via the kit elements. The kit or system can comprise: jumpers, insert nuts, step bushings, bushings, threaded head screws or cylinder head screws, screw plugs, connecting screws, and sockets for integration 3.sup.rd party elements to the laminated electric circuit.

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.

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.

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.

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.

A fastening device for fastening a DIN rail to a wall includes: at least one fastening element having a wall fastening portion for fastening the fastening element to the wall, and a DIN rail fastening portion for fastening the fastening element to the DIN rail. When in a fastened state, the DIN rail fastening portion is guided at least in some regions through an opening formed in the DIN rail. The DIN rail fastening portion includes a tongue and groove system into which a portion of the DIN rail is inserted in the fastened state.

The invention relates to a mounting plate arrangement with a switch cabinet frame and a mounting plate fastened thereto via at least one mounting plate holder, wherein the switch cabinet frame has a rectangular floor frame with four profile struts, which has on its outer side a fastening section offset relative to an outer sealing plane of the switch cabinet frame relative to the interior of the switch cabinet frame, wherein the mounting plate holder is formed in multiple parts, with a support bracket and with a base connected to the support bracket, wherein the support bracket is connected to the fastening section and to the mounting plate and the mounting plate stands on the base, and wherein the mounting plate holder with the base is placed on a profile side of one of the four profile struts extending between the sealing plane and the fastening section.

An adapter for installing electrotechnical components includes: a standardized support rail having a top-hat rail, and which has fastening means on an upper face thereof for installing an electrotechnical component, and fastening means on a bottom face thereof for installing on a front panel of an electrotechnical component. The fastening means on the bottom face have at least one latch hook for latching into a corresponding latch opening on the front panel of the electrotechnical component, and/or the fastening means on the bottom face have at least one snap hook for snapping into a corresponding snap opening on the front panel of the electrotechnical component.
