"These requirements cover electrical power and control cables consisting of either two or more current-carrying copper@ aluminum@ or copper-clad aluminum circuit conductors@ or one or more pairs of thermocouple-extension wires. Thermocouple-extension wires and circuit conductors shall not be mixed in the same cable. These cables are constructed with or without either or both: a) One bare or one or more insulated grounding conductor(s)@ and b) One or more individually jacketed optical-fiber members@ all under an overall jacket. These electrical and composite electrical/optical-fiber cables are intended for use (optical and electrical functions associated in the case of a composite cable) in accordance with Article 336 and other applicable parts of the National Electrical Code (NEC)@ ANSI/NFPA 70 in cable trays@ in raceways@ and where supported in outdoor locations by a messenger wire. The conductors for these cables are described in Sections 9.2 (NEC types) and 9.3 (other conductors). Cables are surface marked with the conductor type letters and/or with the temperature and ""wet""@ ""dry""@ or ""wet or dry"" ratings applicable to the insulation. Cables for direct burial are so marked on the surface. Cables that have a sunlight-resistant jacket are surface marked ""sun res"" or ""sunlight resistant"". Cables may include one or more optical-fiber member(s) and are surface marked to so indicate. Cables that are surface marked ""oil resistant II"" have a jacket that is for exposure to oil at temperatures not in excess of 75??(167??. Cables that are surface marked ""oil resistant I"" have a jacket that is for exposure to oil at temperatures not in excess of 60??(140??. Each insulated conductor that is oil resistant II@ oil resistant I@ VW-1@ gasoline-resistant@ or has another individual conductor use is individually so marked. Cables that are surface marked ?-ER? are for use as exposed runs between a cable tray and utilization equipment where the cables are continuously supported and protected against physical damage using mechanical protection such as struts@ angles@ or channel. The overall jacket on these cables is a ""gas/vapor-tight continuous sheath"" in the sense discussed in Sections 501.15(D) and 501.15(E) of the NEC (see 12.1.1). However@ these requirements do not cover investigation of these cables for transmission of gases or vapors through the core so@ when these cables are used in a hazardous location@ they may need to be sealed as described in the NEC. These cables may contain one or more metal shields but do not have a metal sheath or armor. Electrical cables with a metal sheath or armor are covered as Type MC in the Standard for Metal-Clad Cables@ UL 1569. Connectors and other fittings for these cables are covered in the Standard for Conduit@ Tubing@ and Cable Fittings@ UL 514B. These requirements do not cover the optical or other performance of any optical-fiber member or group of such members."
