Think You Speak Electrician? Prove It!In "TN-S" low-voltage systems, what does "S" indicate?100% Correct Incorrect TN-S systems use independent PE and N conductors, enhancing safety over TN-C (combined PEN). In "TN-S" low-voltage systems, what does "S" indicate? No grounding 3-phase 3-wire system Separate Protective Earth (PE) and Neutral (N) conductors Shared conductor 100%
