Conductors and Grounding

Grounding is accomplished by a conductor connected between electrical equipment or a circuit and the earth. This chapter focuses on various types of wiring and terminations, and grounding. It begins with a definition of the component, followed by units of measure, material and labor requirements, and a takeoff procedure. Armored cable is a fabricated assembly of approved cable with an aluminum or galvanized metal enclosure. Shielded power cables are required in systems where the voltage is 5 kV or above. Mineral insulated cable can be used in hot or cold, wet or dry locations, and in hazardous areas. Nonmetallic sheathed cable is a category that includes a variety of individual types. Estimating the cost of a fiber‐optic system is more complex than most other types of conductors. An undercarpet telephone system is designed to connect telephone devices to a distribution closet using undercarpet cabling.
