2. Ground and neutral - Wikipedia

   en.wikipedia.org/wiki/Ground_and_neutral

   Neutral is a circuit conductor that normally completes the circuit back to the source. NEC states that the neutral and ground wires should be connected at the neutral point of the transformer or generator, or otherwise some "system neutral point" but not anywhere else. [1]

3. NEMA connector - Wikipedia

   en.wikipedia.org/wiki/NEMA_connector

   NEMA L14 are three-pole and ground connectors rated for 125/250 V. Intended for three-pole, four-wire hot-hot-neutral-ground circuits with a nominal supply voltages of 240 or 208 V hot-to-hot and 120 V hot-to-neutral. These connectors are common on household backup generators, and on racks of power amplifiers in large audio systems.

4. Three-prong adaptor - Wikipedia

   en.wikipedia.org/wiki/Three-prong_adaptor

   The ground tab is designed to be attached to the outlet faceplate screw, which is supposed to be connected to the building electrical ground. A cheater plug, AC ground lifter or three-prong/two-prong adapter is an adapter that allows a NEMA 5-15P grounding-type plug (three prongs) to connect to a NEMA 1-15R non-grounding receptacle (two slots).

5. Industrial and multiphase power plugs and sockets - Wikipedia

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

   Higher current plugs have more lugs to prevent them from being inserted into a lower current socket outlet, while still allowing them to be inserted into a socket outlet of the same size group rated for a higher current. For example, a 32 A 4-pin plug without neutral can plug into a 50 A 5-pin socket with neutral available.

6. Electrical wiring in North America - Wikipedia

   en.wikipedia.org/wiki/Electrical_wiring_in_North...

   Hot is any line or neutral conductor (wire or otherwise) connected with an electrical system that has electric potential relative to electrical ground or line to neutral. Ground is a safety conductor with a low impedance path to earth. It is often called the "ground wire," or safety ground. It is either bare or has green insulation. [1]

7. Camlock (electrical) - Wikipedia

   en.wikipedia.org/wiki/Camlock_(electrical)

   The National Electric Code (NEC) only specifies colors for ground and neutral: Green for the equipment grounding (safety) conductor (NEC Article 250.119), and white or grey for the neutral (grounded) conductor (NEC Article 200.6). These colors may not be used for any other purpose, nor may their purpose use a different color.

9. Earthing system - Wikipedia

   en.wikipedia.org/wiki/Earthing_system

   In a TN (terra–neutral) earthing system, one of the points in the supply transformer is directly connected with Earth, usually the neutral-star-point in a star-connected supply transformer, the same point from which a neutral (N) connection would be provided. Exposed-conductive-parts within a consumer installation are connected with Earth via ...
