In an IEC-style TN-C-S earthing system, what happens to the PEN (Protective Earth & Neutral) conductor when it enters the customer premises?
Answers
AIt continues as a single wire to every electrical outlet
BIt is connected directly to the water pipe and eliminated
CIt is tied to phase L3 to balance the load
DIt is split into separate Neutral (N) and Protective Earth (PE) conductors at the main panel
