  2. Multiway switching - Wikipedia

    en.wikipedia.org/wiki/Multiway_switching

    In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location.A common application is in lighting, where it allows the control of lamps from multiple locations, for example in a hallway, stairwell, or large room.

  3. Disconnector - Wikipedia

    en.wikipedia.org/wiki/Disconnector

    In electrical engineering, a disconnector, disconnect switch or isolator switch is a type of switching device with visible contacts, used to ensure that an electrical circuit is completely de-energized for service or maintenance.

    A pole will be either a neutral [12] connection or a line [13] Neutral is usually very near to earth potential, usually being earthed either at the distribution board or at the substation. Line (also known as phase or hot, and commonly, but technically incorrectly, as live) carries the full supply voltage relative to the neutral (and to earth).

  5. ISO standards for trailer connectors - Wikipedia

    en.wikipedia.org/wiki/ISO_standards_for_trailer...

    Australia uses basically the same wiring with the exception for pin 5 and pin 2. The problematic part here is that pin 5 is used for trailer brake which means that if you for some reason connect an Australian trailer to a towing vehicle with ISO wiring you will get into trouble with the trailer brakes being applied as soon as you turn on the ...

  6. Trailer connectors in North America - Wikipedia

    en.wikipedia.org/wiki/Trailer_connectors_in...

    If you have a trailer with a lot of lights the diode and relay wiring is preferred, but if you have a trailer with a simple light arrangement it is usually sufficient to wire to 58L. In market there are many special converters [ 1 ] [ 2 ] [ 3 ] that solves the problem of connecting a car with European wiring to a trailer with North American wiring.

  7. Single-wire earth return - Wikipedia

    en.wikipedia.org/wiki/Single-wire_earth_return

    Single-wire earth return (SWER) or single-wire ground return is a single-wire transmission line which supplies single-phase electric power from an electrical grid to remote areas at lowest cost. The earth (or sometimes a body of water) is used as the return path for the current, to avoid the need for a second wire (or neutral wire ) to act as a ...

  8. High-leg delta - Wikipedia

    en.wikipedia.org/wiki/High-leg_delta

    Center-tapped delta transformer Center-tapped delta transformer voltages. High-leg delta service is supplied in one of two ways. One is by a three-phase transformer (or three single-phase transformers), having four wires coming out of the secondary, the three phases, plus a neutral connected as a center-tap on one of the windings.

  9. Hot stick - Wikipedia

    en.wikipedia.org/wiki/Hot_stick

    A linesman working for Country Energy in Australia closing a circuit using a hot stick. In the electric power distribution industry, a hot stick is an insulated pole, usually made of fiberglass, used by electric utility workers when engaged on live-line working on energized high-voltage electric power lines, to protect them from electric shock.
