These IEC60309 power cords are the recommended cords used to connect computing, communications, laboratory, or industrial equipment to high-fidelity IEC60309 power sources. On one end, these cords connect to any 32A-250V female IEC60309 wall outlet or connector, and on the other end they connect to any 32A-250V IEC60309 male plug. These power cords could be considered extension cords because they increase the range (length) for your equipment or devices from the power source.
