How many conductors does a 220V snakebite have?

Explanation:
In a 220V system that uses a grounded plug, you typically have three conductors: live, neutral, and protective earth. The live and neutral carry the voltage to power the device, while the earth provides a safe path to ground in case of insulation fault, helping protective devices trip and reducing the risk of shock. The earth conductor is present for safety even though it doesn’t normally carry current. So a 220V snakebite plug is a three-pin, three-conductor connection: L, N, and E.
