適用范圍：1.1 These requirements cover round or flat metal-clad cables that contain 18 AWG – 2000 kcmil insulated circuit conductors with or without one or more optical-fiber members, all enclosed in armor consisting of interlocked metal strip or a smooth or corrugated metal tube. Round cables contain one or more insulated circuit conductors. Flat cable contains two or three insulated circuit conductors. These electrical and hybrid electrical/optical-fiber cables are for use (optical and electrical functions associated in the case of a hybrid cable) as Type MC cable in accordance with Article 330 and other applicable parts of the National Electrical Code.1.2 These requirements cover round or flat armored cables that have thermoplastic or thermosetinsulation and are for use at potentials not exceeding 600 V (thermoplastic) or 600 or 2000 V (thermoset) where subjected to temperatures not exceeding 75°C (167°F) or 90°C (194°F), depending upon the voltage and temperature ratings of the circuit conductors in the cable. Cables with 600 V conductors that also include one or more optical-fiber members have 2-OF2 supplementing the type letters and are limited to carrying optical energy that has been ruled not hazardous to the human body.1.3 Type MV (medium-voltage) cables rated for 5000 – 35000 V are covered in separate requirements.A multiple-conductor Type MV cable with a smooth (other than lead) or corrugated metal sheath or withinterlocked metal armor may be marked for use also as Type MC cable.1.4 These requirements do not cover Type AC armored cables (see the Standard for Armored Cables,UL 4). Metal-clad cables for use in Division 1 and Zone 1 hazardous locations are required to comply with this standard and the Standard for Metal-Clad Cables and Cable-Sealing Fittings for Use in Hazardous (Classified) Locations, UL 2225.1.5 These requirements do not cover the optical or other performance of any optical-fiber member orgroup of such members. See 8.3.1.6 A cable to which the designation 2ST12 (signifying 2limited smoke2) is applied as a type-letter suffix, complies with the test criteria for smoke release and for cable damage height stated in the Standard for Vertical-Tray Fire-Propagation and Smoke-Release Test for Electrical and Optical-Fiber Cables, UL 1685. See Section 30 (test requirement) and 38.1 (marking requirement) of Metal-Clad Cables, UL 1569.1.7 Deleted March 6, 2003
