1 Scope 1 .1 This Standard specifies the requirements for single-conductor and multiple-conductor thermoset-insulated wires and cables rated 600 V, 1 000 V, 2000 V, and 5000 V, for use in accordance with the rules of the Canadian Electrical Code (CEC), Part 1 , CSA C22.1 , in Canada, Standard for Electrical Installations , NOM-001 -SEDE, in Mexico, and the National Electrical Code (NEC) , NFPA-70, in the United States of America. See Annex A for the complete list of types covered by this Standard and the specific electrical codes for which they are intended, and Annex B for a summary of construction and test requirements for these types. 1 .2 Table 1 provides a summary of the maximum conductor temperature, voltage ratings, and the number of insulated conductors for the types to which this Standard applies. 1 .3 This Standard also specifies the requirements for submersible pump cables, with or without jackets, in Clause 7. No type-letter designations are assigned to these cables. 1 .4 Products within this Standard may have applications not covered by the electrical codes listed in Clause 1 .1 .
2 Definitions 2.1 The following definitions apply in this Standard: Composite insulation system – a multiple-layer system of materials that fulfills the requirements for both electrical and mechanical integrity of the cable or wire. CP – a thermoset compound whose characteristic constituent is chlorosulfonated polyethylene. CPE – a thermoset compound whose characteristic constituent is chlorinated polyethylene. EPCV – a thermoset compound whose characteristic constituent is a co-vulcanizate of ethylene and propylene with polyethylene. EP – a thermoset compound whose characteristic constituent is a copolymer of ethylene and propylene, or a terpolymer of ethylene, propylene, and a small amount of nonconjugated diene, or a blend of both. Equipment-grounding conductor – a conductor that is defined in the National Electrical Code and the Standard for Electrical Installations as ″Grounding Conductor, Equipment″, and defined in the Canadian Electrical Code , Part I, as ″Bonding conductor″. NBR/PVC – a thermoset compound whose characteristic constituents are acrylonitrile butadiene rubber and polyvinyl chloride. Neoprene – a thermoset compound whose characteristic constituent is polychloroprene.
3 General 3.1 Units of measure The unit of measure shall be SI. If a value for measurement is followed by a value in other units in parentheses, the second value represents a direct conversion or an alternative value. Except for conductor size, the first stated value is the requirement. 3.2 Reference publications 3.2.1 Where reference is made to ANCE, CSA, or UL Standards, such reference shall be considered to refer to the latest edition and all amendments published to that edition. ANCE Standards NOM-001 -SEDE Standard for Electrical Installations NMX-E-034-SCFI Plastics Industry – Carbon Black Contents on Polyethylene Materials – Test Method NMX-J-008-ANCE Tinned Soft or Annealed Copper Wire for Electrical Purposes – Specifications NMX-J-01 2-ANCE Wires and Cables – Concentric Lay Stranded Copper Conductors for Electrical Purposes – Specifications NMX-J-01 3-ANCE Wires and Cables – Rope Lay Stranded Copper Conductors Having Concentric Stranded Members for Electrical Purposes – Specifications NMX-J-01 4-ANCE Wires and Cables – Rope Lay Stranded Copper Conductors Having Bunch Stranded Members for Electrical Purposes – Specifications
4.1 .2.1 In Mexico, thermoset-insulated aluminum conductors are limited to sizes 6 AWG and larger in accordance with NOM-001 -SEDE, Standard for Electrical Installations . 4.1 .3 Copper-clad aluminum conductors In the United States, the requirements of Annex D shall apply to solid conductors or the individual wires of stranded conductors prior to stranding. In Canada and Mexico, copper-clad aluminum conductors shall not be used in thermoset-insulated wires and cables. 4.1 .4 Copper conductors 4.1 .4.1 General The requirements of Clauses 4.1 .4.2 or 4.1 .4.3 shall apply to solid conductors or the individual wires of stranded conductors prior to stranding. If the insulation adjacent to a copper conductor is of a material that corrodes unprotected copper, as determined by the requirement in Clause 5.7, or if a protective separator in compliance with Clause 4.1 .8 is not provided, the solid conductor and each of the individual strands of a stranded conductor shall be separately covered with a coating as described in Clause 4.1 .4.2. 4.1 .4.2 Coated copper conductors 4.1 .4.2.1 Each tin-coated conductor shall comply with the requirements of ASTM B33 or NMX-J-008-ANCE; a nickel-coated wire shall comply with ASTM B355, and a silver-coated wire shall comply with ASTM B298. Conductors coated with other metals or alloys shall be subjected to special investigation. Note: In Mexico, the use of ASTM B355 is recommended for nickel-coated wire, and the use of ASTM B298 is recommended for silver-coated wire.UL 44-2010 pdf download.
