Service neutrals should be grounded at the customer's service entrance.

• A. True
• B. False
• C. Sometimes
• D. Never

Answer: (B)

The bond between the neutral and the grounding system is made at the main service equipment, not at random locations downstream. In a properly wired system, the neutral is connected to the grounding electrode system once, at the service disconnect, so that fault currents have a clear return path and the neutral remains near earth potential. If the neutral were grounded at multiple points or at locations other than the main service disconnect, it can create parallel current paths, circulating currents, and shock hazards.

So, grounding the service neutral at the service entrance isn’t the correct practice by itself in every installation; the bond belongs at the main service equipment, and downstream panels must keep neutrals isolated from grounds. That’s why the statement is considered not correct.
