IEC 60320 is an international standard that specifies the dimensions and performance requirements for appliance couplers used in electrical devices. These couplers are essential for connecting power cords to appliances, ensuring safe and reliable electrical connections. The standard covers various types of connectors, including those used in household and commercial equipment. The International Electrotechnical Commission (IEC) developed this standard to promote compatibility and safety across different electrical products. By adhering to IEC 60320, manufacturers can ensure that their appliances can be easily connected to power sources, reducing the risk of electrical hazards and improving user convenience.
