In an electrical system, what is the difference between neutral and ground, and what is the typical voltage difference between them during normal operation?

• A. Neutral carries current; ground provides a fault return path; typically near 0 V difference during normal operation.
• B. Neutral is the reference point for the load; ground carries current during normal operation; typically 120 V difference.
• C. Neutral is connected to earth at the service panel; ground is the insulated conductor carrying current; typically 240 V difference.
• D. Neutral and ground are the same conductor in most systems; difference is zero always.

Answer: (A)
