Cable Installation Manual for Power and Control Cables July 2026 85 7.1.1 NEC (cont’d) Grounding Conductor, Equipment (EGC). The conductive path installed to connect normally non- current-carrying metal parts of equipment together and to the system grounded conductor, to the grounding electrode conductor, or both. FPN No. 1: It is recognized that the equipment grounding conductor also performs bonding.FPN No. 2: See 250.118 for a list of acceptable equipment grounding conductors. Location, Damp. Locations protected from weather and not subject to saturation with water or other liquids but subject to moderate degrees of moisture. Examples of such locations include partially protected locations under canopies, marquees, roofed open porches, and like locations, and interior locations subject to moderate degrees of moisture, such as some basements, some barns, and some cold-storage warehouses. Location, Dry. A location not normally subject to dampness or wetness. A location classified as dry may be temporarily subject to dampness or wetness, as in the case of a building under construction. Location, Wet. Installations underground or in concrete slabs or masonry in direct contact with the earth; in locations subject to saturation with water or other liquids, such as vehicle washing areas; and in unprotected locations exposed to weather. Messenger-Supported Wiring. (NEC 396.2) An exposed wiring support system using a messenger wire to support insulated conductors by any one of the following: (1) A messenger with rings and saddles for conductor support (2) A messenger with a field-installed lashing material for conductor support (3) Factory-assembled aerial cable (4) Multiplex cables utilizing a bare conductor, factory assembled and twisted with one or more insulated conductors, such as duplex, triplex, or quadruplex type of construction Raceway. An enclosed channel of metal or nonmetallic materials designed expressly for holding wires, cables, or busbars, with additional functions as permitted in this Code. Raceways include, but are not limited to, rigid metal conduit, rigid nonmetallic conduit, intermediate metal conduit, liquidtight flexible conduit, flexible metallic tubing, flexible metal conduit, electrical nonmetallic tubing, electrical metallic tubing, underfloor raceways, cellular concrete floor raceways, cellular metal floor raceways, surface raceways, wireways, and busways. 7.1.2 CEC Definitions are contained in Section 0 of the CEC, Part I. Aluminum-sheathed cable – a cable consisting of one or more conductors of approved type assembled into a core and covered with a liquid- and gas-tight sheath of aluminum or aluminum alloy. Ampacity – the current-carrying capacity of electric conductors expressed in amperes.
