What color goes where in a 230v plug?

In a 230V plug, the standard color coding is as follows: the brown wire is the live (L) wire, the blue wire is the neutral (N) wire, and the green/yellow striped wire is the earth (E) wire. The live wire carries the current, the neutral wire returns it, and the earth wire provides a safety path in case of a fault. Always ensure proper connections and safety measures when dealing with electrical installations.
