2. DIN rail - Wikipedia

   en.wikipedia.org/wiki/DIN_rail

   Cross section view of a G-type DIN rail, with electrical equipment mounted on it. G-type rail (according to EN 50035 (abrogated), BS 5825, DIN 46277-1). G rail is generally used to hold heavier, higher-power components. It is mounted with the deeper side at the bottom, and equipment is hooked over the lip, then rotated until it clips into the ...

3. Distribution board - Wikipedia

   en.wikipedia.org/wiki/Distribution_board

   A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.

4. Electrical wiring - Wikipedia

   Terminal blocks for joining aluminium and copper conductors. The terminal blocks may be mounted on a DIN rail. Aluminium wire was common in North American residential wiring from the late 1960s to mid-1970s due to the rising cost of copper. Because of its greater resistivity, aluminium wiring requires larger conductors than copper.

7. Common rail (electricity) - Wikipedia

   en.wikipedia.org/wiki/Common_rail_(electricity)

   In electrical engineering, a common rail (shortened to COM) is a shared path between different electrical routes in an electrical circuit.For example, a device or circuit board might have a power rail or a ground rail, which components are attached to, so all the electrical charge flowing through different components is drawn from/collected into a single conductor line.
