1.1 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:
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 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
70-2002 in cable trays, in raceways, and where supported in outdoor
locations by a messenger wire.
1.2 The conductors for these cables are described in Sections 8.2
(NEC types) and 8.3 (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 mineral oil at
temperatures not in excess of 75?C (167?F). 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 (140?F). 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.
1.3 The overall jacket on these cables is a "gas/vapor-tight continuous
sheath" in the sense discussed in Sections 501.5(D) and 501.5(E) of
the NEC (see 11.1.1). 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.
1.4 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).
1.5 Connectors and other fittings for these cables are covered in the
Standard for Fittings for Cable and Conduit (UL 514B).
1.6 These requirements do not cover the optical or other performance
of any optical-fiber member or group of such members.
