  • SCOPE

    1 Scope

    1.1 This Standard specifies the requirements for single-conductor and multiple-conductor thermoset-insulated wires and cables rated 600 V, 1000 V, 2000 V, and 5000 V, for use in accordance with the rules of the Canadian Electrical Code CE Code Part I, 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.


    1.1 revised February 9, 2015

    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 might have applications not covered by the electrical codes listed in Clause 1.1.
