1 Scope<\/b><\/p>\n
1.1 These requirements cover Type ITC instrumentation control cables consisting of two or more current-carrying copper or thermocouple alloy conductors with or without either or both:<\/p>\n
a)\u00a0Grounding conductor(s), bare or insulated, and<\/p>\n<\/li>\n
b)\u00a0One or more optical-fiber members, all under an overall jacket.<\/p>\n<\/li>\n<\/ol>\n
These electrical and composite electrical\/optical-fiber cables are intended for use (optical and electrical functions associated in the case of a hybrid cable) on circuits rated 150 V or less and 5 A or less in accordance with Article 727 and other applicable parts of the National Electrical Code (NEC).<\/p>\n
\n
1.2 These cables are rated 300 V but are not so marked. Cables for direct-burial are so marked. Jacketed Type ITC cables comply with one of the following 70,000 Btu\/h (20.5 kW) vertical-tray flame tests:<\/p>\n
a)\u00a0The UL test referenced in 1 \u2013 2 of these requirements. These paragraphs apply the test method described as the UL Flame Exposure (smoke measurements are not applicable) in the Standard for Vertical-Tray Fire-Propagation and Smoke-Release Test for Electrical and Optical-Fiber Cables, UL 1685<\/b>.<\/p>\n<\/li>\n b)\u00a0The FT4\/IEEE 1202 test referenced in 1 of these requirements. This paragraph applies the test method described as the FT4\/IEEE 1202 Type of Flame Exposure (smoke measurements are not applicable) in UL 1685.<\/p>\n<\/li>\n c)\u00a0For limited-smoke cable, either the UL test or the FT4\/IEEE 1202 test referenced in 1 and 2 of these requirements. These paragraphs apply the test methods described in UL 1685 with smoke measurements included.<\/p>\n<\/li>\n<\/ol>\n \n 1.3 A cable that contains one or more electromagnetic shields may be surface marked or have a marker tape to indicate that it is "shielded". A cable that contains one or more optical-fiber members has "-OF" supplementing the type letters and is limited (see 3) to carrying optical energy that has been ruled not hazardous to the human body.<\/p>\n<\/p>\n \n 1.4 All Type ITC cables qualify for exposure to sunlight (a 720-hour sunlight-resistance test is required \u2013 see 1). A marking is not required; however, where used, the marking consists of "sun res" or "sunlight resistant" on the tag and either on the overall cable jacket or legible through the jacket [see 1(i)].<\/p>\n<\/p>\n \n 1.5 These cables may have a metal sheath or armor over the required non\/metallic jacket.<\/p>\n<\/p>\n \n 1.6 These requirements do not cover the optical or other performance of any optical-fiber member or group of such members.<\/p>\n<\/p>\n \n 1.7 The overall jacket on Type ITC cable is a "gas\/vapor-tight continuous sheath" in the sense discussed in Sections 501.15 (D) and 501.15 (E) of the National Electrical Code, ANSI\/NFPA 70, (see 1).<\/p>\n<\/p>\n \n 1.8 Cables that are surface marked "-ER" are for use as exposed runs of not more than 50 ft (15.2 m) between a cable tray and equipment where the cables are supported and secured every 6 ft (1.8 m).<\/p><\/p>\n","protected":false},"excerpt":{"rendered":" Standard for Instrumentation Tray Cable<\/b><\/p>\n\n\n
