UL 1309:2017 Marine Shipboard Cable.
1.1 UL 1309 specifies the requirements for distribution (power) cables, and control and signal cables for installation aboard marine vessels, fixed and floating offshore petroleum facilities, and mobile offshore drilling units (MODUs), in accordance with industry installation standards and the regulations of the authorities having jurisdiction. The cables are single or multi-conductor, with or without metal armor and/or jacket, and are rated 300 V — 35 kV.
1.2 These cables are not intended for use in accordance with the National Electrical Code (NEC), ANSI/NFPA 70. Cables that also meet the requirements for use with the NEC may be additionally marked with the appropriate “Type” designation from the NEC.
2 Units of Measurement
2.1 In addition to being stated in the inch/pound units that are customary in the USA, each of the requirements in this standard is also stated in units that make the requirement conveniently usable in countries employing the metric system (practical SI). Equivalent — although not necessarily exactly identical — results are to be expected from applying a requirement in USA or metric terms. Equipment calibrated in metric units is to be used when a requirement is applied in metric terms.
3 References
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.
4 Copper Conductors
4.1 General
4.1.1 All conductors shall be of soft annealed stranded copper wire. The conductors may be tinned or alloy coated where necessary to ensure compatibility with primary insulation. Conductor sizes and resistances shall comply, within allowable tolerances, with the Reference Standard for Electrical Wires, Cables, and Flexibte Cords, UL 1581.
4.2 Composition
4.2.1 Stranded conductors shall comply with the requirements of the Standard Specification for Soft or Annealed Copper Wire, ASTM B3; the Standard Specification for Concentric-Lay-Stranded Copper Conductors, Hard, Medium-Hard, or Soft, ASTM B8; the Standard Specification for Tin-Coated Soft or Annealed Copper Wire for Electrical Purposes, ASTM B33; the Standard Specification for Rope-Lay-Stranded Copper Conductors Having Bunch-Stranded Members, for Electrical Conductors, ASTM B172; the Standard Specification for Rope-Lay-Stranded Copper Conductors Having Concentric-Stranded Members, for Electrical Conductors, ASTM Bi 73; the Standard Specification for Bunch-Stranded Copper Conductors for Electrical Conductors, ASTM Bi 74; the Standard Specification for Lead-Coated and Lead-Alloy-Coated Soft Copper Wire for Electrical Purposes, ASTM Bi 89; the Standard Specification for Compact Round Concentric-Lay-Stranded Copper Conductors, ASTM B496; or the Standard Specification for 19 Wire Combination Unilay-Stranded Copper Conductors for Subsequent Insulation, ASTM B787; as applicable. Metric sizes complying with Conductors of Insulated Cables, IEC
60228 are acceptable.UL 1309 pdf download.
