Preface This is the common CSA and UL standard for insulated multi-pole splicing wire connectors. It is the first edition of CSA C22.2 No. 2459 and the first edition of UL 2459. 1 Scope 1.1 This Standard covers insulated multi-pole mating or non-mating splicing wire connectors intended for field wiring and factory wiring for use in accordance with the Canadian Electrical Code, Part I, in Canada, and NFPA 70, National Electrical Code, in the United States. 1.2 These wire connectors are intended to facilitate the connection of devices, such as prefabricated wiring assemblies, smoke detectors, and lighting products, to the branch circuit conductors of buildings. 1.3 These wire connectors may additionally be used internal to luminaries to facilitate replacement of the ballast and may not be directly attached to the branch circuit conductors. These wire connectors are suitable for one or more conductors per contact. 1.4 These wire connectors are suitable for use with 30 to 6 AWG (0.05 to 13.3 mm2) stranded copper conductors and 30 to 10 AWG (0.05 to 5.3 mm2) solid copper conductors. 1.5 These wire connectors are suitable for currents not exceeding the ampacity of insulated conductors as rated by the manufacturer. Note: The ampacity of insulated conductors 14 AWG (2.1 mm2) and larger is determined in accordance with the values in the "Assigned maximum ampere rating" column, under the heading "Copper", in Table 7 of CAN/CSA-C22.2 No. 65 or UL 486A-486B. In Canada, the maximum ampacity of insulated conductors 14 AWG (2.1 mm2) and smaller is determined in accordance with Table 12 of the Canadian Electrical Code, Part I. 1.6 These wire connectors are suitable for voltages not exceeding 600 V. 1.7 This Standard does not apply to (a) splicing wire connectors intended for direct burial; (b) insulated splicing wire connectors intended for use at voltage levels exceeding 600 V (1000 V in a sign or luminaire); (c) terminal wire connectors; (d) wire binding screw terminals; (e) built-in terminal connectors on devices having integral cable clamps; (f) flat quick-connect terminals; (g) devices, such as wire connectors and soldering lugs, that are covered by (1) CAN/CSA-C22.2 No. 65 or UL 486A-486B; (2) CAN/CSA-C22.2 No. 188 or UL 486C; or (3) UL 486 E; (h) devices, such as quick-connect terminals, that are covered by CSA C22.2 No. 153 or UL 310; (i) devices covered by CSA C22.2 No. 182.3 or UL 1977; and (j) devices, such as pin and sleeve connectors, that are covered by CSA C22.2 No. 182.1 or UL 1682.
