This is the harmonized CSA and UL standard for Appliance Couplers For Household And Similar General
Purposes – Part 1: General Requirements. It is the first edition of CAN/CSA-C22.2 No. 60320–1 and the
and the second edition of UL 60320–1. This standard is based on IEC 60320–1, Edition 2.1: 2007 (edition
2: 2001 consolidated with amendment 1: 2007). 1 Scope This part of IEC 60320 is applicable to two-pole appliance couplers for a.c. only, with or without earthing
contact, with a rated voltage not exceeding 250 V and a rated current not exceeding 16 A, for household
and similar general purposes and intended for the connection of a supply cord to electrical appliances or
other electrical equipment for 50 Hz or 60 Hz supply. NOTE 1 Appliance inlets integrated or incorporated in appliances or other equipment are within the scope of this standard. The
dimensional and general requirements of this standard apply to such inlets, but certain tests may not be relevant. NOTE 2 The requirements for connectors are based on the assumption that the temperature of the pins of the corresponding
appliance inlets does not exceed 70 °C for connectors for cold conditions;
120 °C for connectors for hot conditions;
155 °C for connectors for very hot conditions. NOTE 3 Appliance couplers complying with this standard are suitable for use at ambient temperatures not normally exceeding 25
°C, but occasionally reaching 35 °C. NOTE 4 Appliance couplers complying with the standard sheets in this standard are intended for the connection of equipment having
no special protection against moisture. If appliance couplers are used with equipment which may be subject to spillage of liquid in
normal use then protection against moisture is to be provided by the equipment. NOTE 5 Special constructions may be required
– in locations where special conditions prevail, for example, as in ships, vehicles and the like;
– in hazardous locations, for example, where explosions are liable to occur. 1DV D1 Modify the first paragraph by replacing with the Clauses 1DV.1 and 1DV.2:
1DV.1 These requirements are applicable to two-pole appliance couplers for a.c. only, and
with or without earthing contact, with a rated voltage not exceeding 250 V and a rated
current not exceeding 20 A, for household and similar general purposes and intended for
the connection of a supply cord to electrical appliances or other electrical equipment for
50 Hz or 60 Hz supply. 1DV.2 This standard does not apply directly to the following devices, but supplements the
standards applying to such devices:
– devices produced integrally with flexible cord or cable, which are covered by CSA C22.2
No. 21 and UL 817.
