APPLIANCE COUPLERS FOR HOUSEHOLD AND SIMILAR GENERAL PURPOSES – Part 1: General Requirements

UL 60320-1

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 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.
