UL 1682:2017 Plugs, Receptacles, and Cable Connectors of the Pin and Sleeve Type.
1.1 UL 1682 applies to pin and sleeve type plugs, receptacles, power inlets, and connectors, rated up to 800 amperes and up to 600 volts ac or dc, and which may include up to eight pilot contacts. These devices are intended to provide power from branch circuits, or are for direct connection to the branch circuit in accordance with the Canadian Electrical Code Part I, the National Electrical Code (NEC), ANSI/NFPA 70, and the Mexican Electrical Code, NOM 001 SEDE, using copper conductors, for use in either indoor or outdoor nonhazardous locations. In Canada, the terminals of a device intended to accommodate aluminum conductors also comply with CSA C22.2 No. 65.
1.2 This standard does not apply to single conductor pin and sleeve devices. Single pole locking-type separable connectors are covered by CSA C22.2 No. 1691/UL 1691.
1.3 This standard does not apply to:
a) Devices molded integrally with flexible cord or cable that are covered by UL 817, CSA C22.2 No. 21, and NMX-J-195-ANCE;
b) General and special use devices, such as attachment plugs, receptacles, cord connectors, inlets, current taps, flatiron and appliance plugs, that are covered by UL 498, CSA C22.2 No.
42, CSA C22.2 No. 57, CSA C22.2 No. 182.2, NMX-J-412-ANCE, NMX-J-41212-1-ANCE, NMX
J-41 2/2-2-ANCE, NMX-J-41 2/2-3-ANCE, NMX-J-41 2/2-4-ANCE, NMX-J-41 2/2-5-ANCE, and NMX-J-41 2/2-6-ANCE;
c) Single and multi-pole connectors intended for connection to copper conductors, for use in data, signal, control and power applications within and between electrical equipment, where exposed, that are covered by UL 1977 and CSA C22.2 No. 182.3;
d) Devices intended for use in hazardous (Classified) locations that are covered by UL 1203 and CSA C22.2 No. 159; and
e) Products such as switched interlocks that are covered by UL 508 and CSA C22.2 No. 14. 2 Definitions
2.1 For the purposes of this standard, the following definitions apply.
2.2 CONNECTOR (CABLE CONNECTOR) — A portable receptacle that is intended to provide power, with means for attachment of flexible cord or cable and not intended for permanent mounting.
2.3 CONTACT — A conductive element in a component that mates with a corresponding element to provide an electrical path.
2.4 CONTACT, PILOT — A conductive element intended to carry an indicating or controlling signal.
2.5 DELAYED ACTION — An arrangement that delays the separation of device housings which is intended to reduce the likelihood of exposure of arcing contacts during the breaking of the circuit when the plug is withdrawn.UL 1682 pdf download.
