Equipment
(14) Equipment. A general term which includes materials, fittings, devices, appliances, fixtures, apparatus, and similar items used as part of, or in connection with, a supply or communications installation. (15) Ground (reference). That conductive body, usually earth, to which an electric potential is referenced. (16) Ground (as a noun). A conductive connection, whether intentional or accidental, by which an electric circuit or equipment is connected to reference ground. (17) Ground (as a verb). The connecting or establishment of a connection, whether by intention or accident, of an electric circuit or equipment to reference ground. (18) Ground tent. A small tent usually constructed of vinyl coated canvas supported by a metal or plastic frame. Its purpose is to protect employees from inclement weather while working at buried cable pedestal sites or similar locations. (19) Grounded conductor. A system or circuit conductor which is intentionally grounded. (20) Grounded systems. A system of conductors in which at least one conductor or point (usually the middle wire, or the neutral point of transformer or generator windings) is intentionally grounded, either solidly or through a current-limiting device (not a current-interrupting device). (21) Grounding electrode conductor. (Grounding conductor). A conductor used to connect equipment or the grounded circuit of a wiring system to a grounding electrode. (22) Insulated. Separated from other conducting surfaces by a dielectric substance (including air space) offering a high resistance to the passage of current. (23) Insulation (as applied to cable). That which is relied upon to insulate the conductor from other conductors or conducting parts or from ground. (24) Joint use. The sharing of a common facility, such as a manhole, trench or pole, by two or more different kinds of utilities (e.g., power and telecommunications). (25) Ladder platform. A device designed to facilitate working aloft from an extension ladder. A typical device consists of a platform (approximately 9 18) hinged to a welded pipe frame. The rear edge of the platform and the bottom cross-member of the frame are equipped with latches to lock the platform to ladder rungs. (26) Ladder seat. A removable seat used to facilitate work at an elevated position on rolling ladders in telecommunication centers. (27) Manhole. A subsurface enclosure which personnel may enter and which is used for the purpose of installing, operating, and maintaining submersible equipment and/or cable. (28) Manhole platform. A platform consisting of separate planks which are laid across steel platform supports. The ends of the supports are engaged in the manhole cable racks. (29) Microwave transmission. The act of communicating or signaling utilizing a frequency between 1 GHz (gigahertz) and 300 GHz inclusively. (30) Nominal voltage. The nominal voltage of a system or circuit is the value assigned to a system or circuit of a given voltage class for the purpose of convenient designation. The actual voltage may vary above or below this value. (31) Pole balcony or seat. A balcony or seat used as a support for workmen at pole-mounted equipment or terminal boxes. A typical device consists of a bolted assembly of steel details and a wooden platform. Steel braces run from the pole to the underside of the balcony. A guard rail (approximately 30 high) may be provided. (32) Pole platform. A platform intended for use by a workman in splicing and maintenance operations in an elevated position adjacent to a pole. It consists of a platform equipped at one end with a hinged chain binder for securing the platform to a pole. A brace from the pole to the underside of the platform is also provided. (33) Qualified employee. Any worker who by reason of his training and experience has demonstrated his ability to safely perform his duties. (34) Qualified line-clearance tree trimmer. A tree worker who through related training and on-the-job experience is familar with the special techniques and hazards involved in line clearance. (35) Qualified line-clearance tree-trimmer trainee. Any worker regularly assigned to a line-clearance tree-trimming crew and undergoing on-the-job training who, in the course of such training, has demonstrated his ability to perform his duties safely at his level of training. (36) System operator/owner. The person or organization that operates or controls the electrical conductors involved. (37) Telecommunications center. An installation of communication equipment under the exclusive control of an organization providing telecommunications service, that is located outdoors or in a vault, chamber, or a building space used primarily for such installations. (38) Telecommunications derricks. Rotating or nonrotating derrick structures permanently mounted on vehicles for the purpose of lifting, lowering, or positioning hardware and materials used in telecommunications work. (39) Telecommunication line truck. A truck used to transport men, tools, and material, and to serve as a traveling workshop for telecommunication installation and maintenance work. It is sometimes equipped with a boom and auxiliary equipment for setting poles, digging holes, and elevating material or men. (40) Telecommunication service. The furnishing of a capability to signal or communicate at a distance by means such as telephone, telegraph, police and firealarm, community antenna television, or similar system, using wire, conventional cable, coaxial cable, wave guides, microwave transmission, or other similar means. (41) Unvented vault. An enclosed vault in which the only openings are access openings. (42) Vault. An enclosure above or below ground which personnel may enter, and which is used for the purpose of installing, operating, and/or maintaining equipment and/or cable which need not be of submersible design. (43) Vented vault. An enclosure as described in paragraph(s) (42) of this section, with provision for air changes using exhaust flue stack(s) and low level air intake(s), operating on differentials of pressure and temperature providing for air flow. (44) Voltage of an effectively grounded circuit. The voltage between any conductor and ground unless otherwise indicated. (45) Voltage of a circuit not effectively grounded. The voltage between any two conductors. If one circuit is directly connected to and supplied from another circuit of higher voltage (as in the case of an autotransformer), both are considered as of the higher voltage, unless the circuit of lower voltage is effectively grounded, in which case its voltage is not determined by the circuit of higher voltage. Direct connection implies electric connection as distinguished from connection merely through electromagnetic or electrostatic induction.
