2. Trailer connectors in North America - Wikipedia

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

   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. What most of these converters do is to bring together the turn signals and stop lamp signal from a three-wire solution using 54, L and R into a two-wire solution using L54 and R54 ...

3. Three-prong adaptor - Wikipedia

   en.wikipedia.org/wiki/Three-prong_adaptor

   [2] [3] These adapters are illegal in some jurisdictions, in particular throughout Canada. [4] A safer and more reliable alternative identified in the US and Canadian electrical codes is to replace the outlet with a Ground Fault Circuit Interrupter (GFCI) breaker outlet. [3] Cheater plugs are also used to break ground loops in audio systems. [5]

4. Circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker

   A shunt-trip unit appears similar to a normal breaker and the moving actuators are ganged to a normal breaker mechanism to operate together in a similar way, but the shunt trip is a solenoid intended to be operated by an external constant-voltage signal, rather than a current, commonly the local mains voltage or DC. These are often used to cut ...

5. Three-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Three-phase_electric_power

   A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line-to-ground voltage because it uses less conductor material to transmit a given amount of electrical power. [3] Three-phase power is mainly used directly to power large induction motors, other electric motors and other ...

7. Residual-current device - Wikipedia

   en.wikipedia.org/wiki/Residual-current_device

   A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...
