It is not recommended to use ordinary plugboard to connect 3kw car charger, because 3kw car charger requires high power supply, and ordinary plugboard can only withstand limited power, easy to cause wire heating, short circuit and even fire and other dangerous situations. The correct approach is to use professional plugs and sockets, or to use an industrial-grade plugboard with overload protection to ensure safe and reliable use of the 3kw onboard charge.
