These requirements cover electrical power and control cables consisting of either two or more current-carrying copper, aluminum, or copper-clad aluminum circuitconductors, 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:
1.One bare or one or more insulated grounding conductor(s), and
2.One or more individually jacketed optical-fiber members, all under an overall jacket.

These electrical and hybrid electrical/optical-fiber cables are intended for use (optical and electrical functions associated in the case of a hybrid cable) in accordancewith Article 340 and other applicable parts of the National Electrical Code (NEC) in cable trays, in raceways, and where supported in outdoor locations by amessenger wire.

The conductors in these cables have 600-V thermoplastic insulation accepted in this application for 200C (392F) on Nos. 18 - 2 AWG conductors; 600-Vthermoplastic insulation accepted in this application for 150C (302F) on Nos. 18 - 4/0 AWG conductors; 2000-V thermoset insulation accepted in this applicationfor 90C (194F) or 75C (167F) on Nos. 14 - 4/0 AWG and 250 - 1000 kcmil conductors; 600-V thermoset insulation accepted in this application for 125C(257F) on Nos. 14 - 4/0 AWG and 250 - 1000 kcmil conductors; or 600-V thermoset or thermoplastic insulation accepted in this application for 90C (194F),75C (167F), or 60C (140F) on Nos. 14 - 4/0 AWG and 250 - 1000 kcmil conductors. Cables are surface marked with the conductor type letters and/or withthe 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 asunlight-resistant jacket are surface marked "sun res" or "sunlight resistant". Cables with 600-V conductors may include one or more optical-fiber member(s) and aresurface marked to so indicate. Cables that are surface marked "oil resistant II" have a jacket that is for exposure to mineral oil at temperatures not in excess of 75C(167F). Cables that are surface marked "oil resistant I" have a jacket that is for exposure to mineral oil at temperatures not in excess of 60?C (140F). Eachinsulated conductor that is oil resistant II, oil resistant I, VW-1, gasoline-resistant, reagent-resistant, or has another individual conductor use is individually so marked.
