Explanation:
IEC 60309 is an international standard from the International Electrotechnical Commission (IEC) for "plugs, socket-outlets and couplers for industrial purposes".
The cable connectors and sockets are colour-coded, according to the voltage range and frequency used; for example, common colours are yellow for 100-130 volts and 50-60 Hz, blue for 200-250 volts and 50-60 Hz, and red for 400-480 volts and 50-60 Hz. Color codes depend on the highest, phase-to-phase, voltage.
