    In both those instances the white wire should be identified as being hot, usually with black tape inside junction boxes. The neutral wire is identified by gray or white insulated wire, perhaps using stripes or markings. With lamp cord wire the ribbed wire is the neutral, and the smooth wire is the hot. NEC 2008 400.22(f) allows surface marking ...

    Hot-wiring, a method of starting a car with no key; Hot-wire foam cutter, a tool used to cut foam and polystyrene; Hot wire (electricity), a wire conductor with non-zero potential in electric power distribution; Hot-wire anemometer, an electrical device for measuring the speed of airflow

  4. Hot-wiring - Wikipedia

    en.wikipedia.org/wiki/Hot-wiring

    Hot-wiring is the process of bypassing a motor vehicle's ignition switch and thus starting it without the key. It is often utilized during a vehicle theft . [ 1 ] However, a legitimate vehicle owner who has lost a vehicle key or starting a vehicle with inoperable ignition switch (e.g. in run-down old cars ) may also implement this process.

    For very high currents in electrical apparatus, and for high currents distributed through a building, bus bars can be used. (The term "bus" is a contraction of the Latin omnibus – meaning "for all".) Each live ("hot") conductor of such a system is a rigid piece of copper or aluminium, usually in flat bars (but sometimes as tubing or other ...

    All NEMA 6 devices are three-wire grounding devices (hot-hot-ground) used for 208 and 240 V circuits and rated for 250 V maximum, with the 6-15, 6-20 and 6-30 being grounding versions of the 2-15, 2-20 and 2-30, respectively. The 6-15 resembles the 5-15, but with collinear horizontal pins, spaced 23 ⁄ 32 in (18.3 mm) center-to-center. The 20 ...

  8. Bridgewire - Wikipedia

    en.wikipedia.org/wiki/Bridgewire

    A bridgewire or bridge wire, also known as a hot bridge wire (HBW), is a relatively thin resistance wire used to set off a pyrotechnic composition serving as pyrotechnic initiator. By passing of electric current it is heated to a high temperature that starts the exothermic chemical reaction of the attached composition.
