conducting. A feeder consists of all circuit conductors located between the service equipment, the source of a separately derived system, or other power supply source and the final branchcircuit overcurrent device. Exception: Overcurrent devices don not have to be readily accessible if located adjacent to the equipment where access is achieved by the use of portable means. The secondary conductors do not extend beyond the enclosure(s) of the (B) Suspended Ceilings. They cant be attached to any fire escape, downspout or plumbing equipment. Office lighting is an example of a continuous load. Overcurrent protection shall not exceed _____. Step 2: Determine the primary overcurrent protection rating [Sec. Accessible (Readily Accessible) Readily accessible means capable of being reached quickly without have to climb or remove obstacles. k=13k51. Separately Derived System B. NEC Requirements for Conductor Material Types and Sizing Requirements, Electrical Troubleshooting Quiz July 19, 2022, NEC Requirements for Overvoltage Protection, EC&M Tech Talk Video Medium-Voltage Conductors and Cable, Monthly Quiz: Grounding and Bonding Connections. Attachment Plug An attachment plug (plug cap) is a device that, when inserted into a receptacle establishes a connection between the conductors of a cord and the receptacle. You are using an out of date browser. Essentially, this Article covers transformers supplying power and lighting loads. A reduction in clearance to 914 mm (3.0 ft) is permitted where the voltage between conductors does not exceed 300 and the roof has a slope of 102 mm (4 in.) The grounding electrode to which the portable equipment system neutral impedance is connected shall be isolated from and separated in the ground by at least 6.1 m (20.0 ft) from any other system or equipment grounding electrode, and there shall be no direct connection between the grounding electrodes, such as buried pipe, fence, and so forth. Where connected to a branch circuit having a rating in excess of 20 amperes, lampholders shall be of the heavy-duty type. 22. There was general agreement that climbing over or under something would render equipment accessible but not readily accessible. So, what does it really cover? In this example, the receptacle is that outlet. Ground-fault detection and relaying shall be provided to automatically deenergize any high voltage system component that has developed a ground fault. Identify and describe the step-by-step process used to install cable in the NCT Colledge buildings? (This category includes conditions covered under the 3.05-m (10.0-ft) category where the voltage exceeds 150 V.). Over residential property and driveways. If the transformer will be set where forklifts might be present, ensure someone installs the correct protection (such as a bollard set into the floor). 100 iops/gb and 100,000 iops per volume oci, Article xi of the code of ethics for professional teacher, The problem of concept drift: definitions and related work, Comparison between micro teaching and traditional teaching, Match the following terms with their definitions communism, Nursing definition by florence nightingale, What is the definition of compare and contrast, Cscmp supply chain management definitions and glossary, Contents Article 1 Article 2 Article 3 Article, Definitions Verbs Adjectives Nouns Genre 100 100 100, Measurement Scientific Definitions Method Graphing 100 100 100, Definitions Adjectives Conjunctions or Interjections 100 100 100, Definitive Article Definite article The The definite article, Contrat Article 60 7 Contrat Article 61 Article, On The Constitution Article 1 Article 2 Article, article definite article indefinite article anaphoric anaphoricity judgement, Definite Article Definite article The The definite article, Modifiers Article Personal Pronoun Article Possessive Pronoun Article, XML article idhw titleHellotitle paraHello objectWorldobjectpara article article, ARTICLE 8 Civil Code of the Philippines Article, 2020 Electrical Advisory Board Article 100 and 200, ORAL PATHOLOGY DEFINITIONS PATHOLOGY DEFINITIONS PATHOLOGY DIAGNOSIS DEFINITIONS, Genetic Definitions Karyotype Genetic Definitions Genetic Definitions Genetic, Electrical Safety Basic Electrical Safety Electrical Course not, Electrical Charge Electrical Force and Electric Fields Electrical, Electrical Technology What is Electrical Technology n Electrical, Electrical Circuits Electrical Circuits l Electrical circuits will. Duplexes control outlets of energy, as well as switches and can be used in conjunction such as a garbage disposal, Enclosed Equipment, conductors, ect. B. Circuit breakers and fuses must be readily accessible [240.24].

Equipment found damaged or defective shall not be used until repaired; The following tests shall be performed on all cord sets and receptacles which are not a part of the permanent wiring of the building or structure, and cord- and plug-connected equipment required to be grounded: All equipment grounding conductors shall be tested for continuity and shall be electrically continuous; Each receptacle and attachment cap or plug shall be tested for correct attachment of the equipment grounding conductor. a. All this can be considered equipmentpretty much anything sold at home depot, Feeder B. Select one: A. An intersystem bonding termination will typically be used as a ground junction for a/anA. 450.13 contains accessibility requirements. Grounded (grounding) is defined as being ____. For dc circuits only, the equipment grounding conductor may be run separately from the circuit conductors. Grounded Conductor Cont B. . Ducts used to transport dust, loose stock, or flammable vapors shall not contain ____ of any type. This rule does not prohibit the locking of panel doors or the placing of a padlock on a circuit breaker to restrict access [110.26]. Basically, ______receptacles are required to be installed if an equipment grounding conductor is available at the outlet where the receptacle is located. Communications conductors alone -- no requirement. Feeder and branch-circuit conductors shall have overcurrent protection in each ungrounded conductor located at the point where the conductor receives its supply or at a location in the circuit determined under engineering supervision; Circuit breakers used for overcurrent protection of three-phase circuits shall have a minimum of three overcurrent relays operated from three current transformers. The noncurrent-carrying metal parts of equipment and the equipment grounding conductor terminals of the receptacles are bonded to the generator frame.
