Socket Terminals and Meanings

  • L (Live): The phase line where electric current is supplied.
  • N (Neutral): The neutral line that completes the circuit and is usually close to zero voltage.
  • PE (Protective Earth): The protective earth line that routes leakage current to ground and reduces shock risk.
  • L1, L2, L3: Phase lines used in three-phase systems for higher and more balanced power transfer.
