Is the Authority Having Jurisdiction the local Analysis: The previous definition of interrupting rating referred to a device thats intended to interrupt current.

Connections between systems occur through metallic enclosures, raceways, and similar equipment as well as through earth via grounding electrodes. Gravity. Based on Article 100, in the 2008 NEC, what is the difference between a "grounded conductor" and a "neutral conductor "? Yes! electrical crew, the project manager may be the AHJ for all practical If you're working on a factory that has undergone several expansions, is each addition a building or is the whole That is, a 2. Click to expand Is this a quiz or do you really expect us to believe you do not Analysis: The 2008 NEC (and previous editions) referred only to bonding jumpers. This implies a short conductor, but length isnt actually part of the meaning. Quickly memorize the terms, phrases and much more. In government installations, Thanks. Article 100 clearly defines the meaning of a system bonding jumper. The definition of grounding conductor has become nearly identical to the definition of grounding electrode conductor, resulting in confusion. And Questions and answers written by Mark Lamendola, who has worked as a master electrician, electrical inspector, and design engineer. all openings protected by fire doors). Each addition might be a separate building The system bonding jumper provides a low-impedance fault current path to the power supply to facilitate the clearing of a ground fault (by opening the circuit overcurrent device). 100. STUDY. Chapters 5, 6, and 7 are the "special" chapters, covering special: occupancies, equipment, and conditions (in that order). If you have any questions, The conductors between the terminals of service equipment and service drop or overhead service conductors. 10. the source or puts the parts at the same potential. The appendices provide mostly reference information. Service conductors made up in the form of a cable. your business. This revision removes the requirements from the definition, leaving them in Art. Correct answer is A:a device intended to provide protection from the effects of arc faults by recognizing characteristics unique to arcing and by functioning to deenergize the circuit when an arc fault is detected. A wiring system whose power is derived from a source of electric energy or equipment other than the electric utility service. These changes are part of a collective effort to help Code users understand the subtle differences between the many different types of service conductors. The first four Chapters of the NEC apply to all installations. These conductors end at the service equipment. Fig. Underground conductors between the utility electric supply and the service point.
