PrefaceThis is the ninth edition of CSA C22.2 No. 127, Equipment and lead wires. It is one of a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. It supersedes the previous editions, published in 2015, 2009, 1999, 1995, 1988, 1981, 1966, and 1964. The major changes to this edition include the following: a) fibrous nonmetallic stranding has been permitted in this Standard (see Clause 5.1.8); b) TXF-S and TXFW-S have been added; c) an additional test for breaking strength has been added (for TXF-S and TXFW-S); and d) the terms "grounded" and "bonded" have changed throughout this Standard for consistency with the definitions in the Canadian Electrical Code, Part I. For general information on the Standards of the Canadian Electrical Code, Part II, see the preface to CAN/CSA-C22.2 No. 0, General Requirements?Canadian Electrical Code, Part II.Scope1.1 This Standard applies to insulated conductors intended for internal wiring of electrical equipment, for leads of transformers, motors, etc., and for luminous-tube signs and ignition systems, to be installed in accordance with the Canadian Electrical Code, Part I. 1.2 Constructions to which this Standard applies are shown in Tables 1 and 2. The Tables are not a complete summary of the construction details, but all of the items shown therein are requirements or limitations. 1.3 The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only. 1.4 In this Standard, "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; and "may" is used to express an option or that which is permissible within the limits of the Standard. 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.
