18、L COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover electrical cables for boats. The cables are intended for use in marine pleasure craft and consist of a single insulated conductor without a jack
19、et or of two or more insulated conductors with or without an overall nonmetallic jacket. Each boat cable is rated as follows: 600 V; 60C (140F), 75C (167F), or 90C (194F) wet; and 60C (140F), 75C (167F), 90C (194F), or 105C (221F) dry. Boat cable dry-rated 125C (257F) or 200C (392F) may be investiga
20、ted. A boat cable so marked has insulation (and jacket if a jacket is used) that is for use where exposed to oil at 60C (140F) and lower temperatures. Boat cables employ stranded copper conductors that are 18 - 4/0 AWG for multiple conductors and 16 - 4/0 AWG for single conductors. 1.2 The ampacity
21、of a boat cable shall be as stated in the US Coast Guard regulations Title 33, Chapter I, Parts 183.430 and 183.435 of the CFR. 2 Units of Measurement 2.1 In addition to being stated in inch/pound units, each numerical requirement in this standard is also stated in units that make the requirement co
22、nveniently usable in the metric system (practical SI). Equivalent although not necessarily exactly identical results are to be expected from applying a requirement in inch/pound or metric terms. Equipment calibrated in metric units is to be used when a requirement is applied in metric terms. 3 Refer
23、ences 3.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. CONSTRUCTION 4 Conductors 4.1 The conductors shall be of stranded soft-annealed copper that complies with the America
24、n Society for Testing and Materials Standard Specication for Soft or Annealed Copper Wire, ASTM B 3. Conductors shall be 18 4/0 AWG. The 18 AWG size is limited to a jacketed multiple-conductor cable and shall employ 16 or more strands. All other conductor sizes shall employ 19 or more strands. Condu
25、ctors may be coated with tin or a tin/lead alloy. An 18 or 16 AWG conductor shall comply with the requirements for conductors in the Standard for Fixture Wire, UL 66. A 14 AWG or larger conductor shall comply with the requirements for copper conductors in the Standard for Thermoplastic-Insulated Wir
26、es and Cables, UL 83.

27、r Thermoplastic-Insulated Wires and Cables, UL 83. In addition, the insulation in a cable that is marked as being oil-resistant shall comply with the requirements for 60C (140F) oil resistance in UL 83. The average and minimum-at-any-point thicknesses shall comply with one of the constructions in Ta
28、ble 5.1 or 5.2. Insulated conductors employing other insulation, wall thicknesses, or temperature ratings may be investigated.

33、e used in the same cable. The length of lay of the cabled conductors is not specied. The conductors in a 2-, 3-, or 4-conductor cable may be laid parallel to form a at cable. The use of llers is optional. The cabled assembly may be enclosed in a braid, tape, or other binder. 9 Shield(s) 9.1 A shield
34、 is not required but is acceptable over an individual insulated conductor, over one or several groups of conductors, or over the entire cable assembly, in a cable with a nonmetallic jacket only. Several shields may be used in a given cable. 10 Nonmetallic Jacket (Optional) 10.1 A jacket of any PVC j
35、acketing material (60C or 140F oil-resistant PVC if the cable is marked as being oil-resistant) mentioned in the Standard for Flexible Cords and Cables, UL 62, may be employed over the at or cabled conductor assembly in a multiple-conductor cable. Single-conductor cable shall not be jacketed. If the
36、 conductor insulation is rated for 60C (140F) or 75C (167F), the jacket shall be of a material having a rating of at least 60C (140F). If the conductor insulation is rated for 90C (194F) or a higher temperature, the jacket may be of a material having a temperature rating 15C or 27F lower than the dr
37、y temperature rating of the conductor insulation. The thicknesses of the jacket shall comply with Table 10.1.

40、Wires, Cables, and Flexible Cords, UL 1581, shall make unaged and aged specimens perform in accordance with the Standard for Thermoplastic-Insulated Wires and Cables, UL 83, for the insulation, and in accordance with the Standard for Flexible Cords and Cables, UL 62, for the jacket. 12 Conductor Cor
41、rosion 12.1 Conductors shall not show any evidence of pitting or corrosion after being tested in accordance with Conductor Corrosion General, Section 500 of the Reference Standard for Electrical Wires, Cables, and Flexible Cords, UL 1581. Bare copper conductors without a metal covering are required
42、to be tested. One specimen is to be conditioned with the conductor in place, in an air oven mentioned in 11.1. 12.2 A specimen not showing any evidence of pitting or corrosion compounds in a close visual examination with normal or corrected vision without magnication is determined to be in complianc
43、e. Normal discoloration not induced by the insulation is to be disregarded. 12.3 Specimens of wire that do not comply with the conductor corrosion test are required to use tinning or other protective metal coating.

45、conductors taken from nished cable are to be wound tightly, with adjacent turns touching, onto metal mandrels. The size of the mandrels and number of turns wound are to be as indicated in Table 13.1 for the test of the individual conductors. For the test of the complete cable, a mandrel ve times the
46、 measured overall diameter of the complete cable or the length of the minor axis of a at cable shall be used. The cable is to be wrapped for not less than 180 around the mandrel. The ends of each specimen are to be secured to the mandrels and the assemblies placed in a full-draft circulating-air ove
