Under arcing conditions, the gases produced, while consisting predominantly of noncombustible hydrogen chloride, can include varying amounts of combustible gases, depending on the askarel type. Study NEC Article 100 Definitions Flashcards Flashcards at ProProfs - This Flashcard quiz is designed to describe the terms and definitions used in the NEC 2008 Article 100. In the 2020 NEC, the Scope of Article 100 was modified to include new Part III which only covers definitions that apply to “Hazardous Classified Locations”. One of the key revisions was a definition of “Reconditioned” which is now defined in Article 100 as “Electromechanical systems, equipment, apparatus, or components that are restored to operating conditions.

A conductor used to connect the system grounded conductor or the equipment to a grounding electrode or to a point on the grounding electrode system. A system intended to provide protection of equipment from damaging line-to-ground fault currents by operating to cause a disconnecting means to open all ungrounded conductors of the faulted circuit. FPN No. A reliable conductor to ensure the required electrical conductivity between metal parts required to be electrically connected. A device designed to open and close a circuit by nonautomatic means and to open the circuit automatically on a predetermined overcurrent without damage to itself when properly applied within its rating. Instantaneous Trip (as applied to circuit breakers). Special Permission. The common point on a wye-connection in a polyphase system or midpoint on a single-phase, 3-wire system, or midpoint of a single-phase portion of a 3-phase delta system, or a midpoint of a 3-wire, direct-current system. Surge Arrester. Type 3: Point of utilization SPDs.

FPN No. It may also include parts to protect the light source or the ballast or to distribute the light. To illustrate how to use Article 220, let’s do a basic load calculation: Load Calculation Exercise . The fuseholder or fuse carrier may include a conducting element (fuse link) or may act as the disconnecting blade by the inclusion of a nonfusible member. An enclosure that is designed for either surface mounting or flush mounting and is provided with a frame, mat, or trim in which a swinging door or doors are or can be hung. A switchgear assembly completely enclosed on all sides and top with sheet metal (except for ventilating openings and inspection windows) and containing primary power circuit switching, interrupting devices, or both, with buses and connections. Askarels of various compositional types are used. FPN: A fuse comprises all the parts that form a unit capable of performing the prescribed functions. Grounding Conductor, Equipment (EGC). Bonding Jumper, Equipment. Circuit Breaker. Where there is no terminal box, meter, or other enclosure, the point of connection is considered to be the point of entrance of the service conductors into the building. Externally Operable. Provided with a means to permit circulation of air sufficient to remove an excess of heat, fumes, or vapors. A flammable liquid having a flash point below 38°C (100°F), or a flammable liquid whose temperature is above its flash point, or a Class II combustible liquid that has a vapor pressure not exceeding 276 kPa (40 psia) at 38°C (100°F) and whose temperature is above its flash point.
