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. Welding power supply - Wikipedia

   en.wikipedia.org/wiki/Welding_power_supply

   A transformer-style welding power supply converts the moderate voltage and moderate current electricity from the utility mains (typically 230 or 115 VAC) into a high current and low voltage supply, typically between 17 and 45 (open-circuit) volts and 55 to 590 amperes.

4. 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.

5. 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.

6. Industrial and multiphase power plugs and sockets - Wikipedia

   en.wikipedia.org/wiki/Industrial_and_multiphase...

   The yellow 2P+E 16 A version carrying 115 V is used extensively on the London Underground railway system to power temporary usage of heavy-duty fans; it is also frequently used by tradesmen within the UK, built into a portable transformer box that is powered from a standard 13 A 240 V mains supply, to run heavy-duty power-tools designed to ...

7. Power supply - Wikipedia

   en.wikipedia.org/wiki/Power_supply

   An external power supply, AC adapter or power brick, is a power supply located in the load's AC power cord that plugs into a wall outlet; a wall wart is an external supply integrated with the outlet plug itself. These are popular in consumer electronics because of their safety; the hazardous 120 or 240 volt main current is transformed down to a ...
