Scope
1.1This Standard specifies requirements for Type NS75 and NS90 neutral supported cables for use on outdoor overhead electrical systems that have nominal voltages of 600 V or less for installation in accordance with the Canadian Electrical Code, Part I.
1.2Neutral supported cables covered by this Standard consist of up to five conductors (one, two, or three insulated phase conductors, a neutral conductor, and an optional insulated control/supply conductor). The conductors are insulated with polyethylene (PE) rated 75 degrees C or cross-linked polyethylene (XLPE) rated 75 or 90 degrees C.
1.3Flame test requirements for neutral supported cable insulations or coverings are also included where called for by the Canadian Electrical Code, Part I.
1.4In CSA Standards, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; “may” is used to express an option or that which is permissible within the limits of the standard; and “can” is used to express possibility or capability. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
