The first disconnecting means is the location where the Neutral-to-Ground bond is permissible.

• A. True
• B. False
• C. Not specified
• D. Only at service entrance

Answer: (A)

Bonding the neutral to ground is allowed at a single point, and that point is the first disconnecting means in the system. This is typically the main service disconnect or service equipment where the utility service enters the building. Establishing the bond there ensures a single reference for grounding and prevents current from traveling on the equipment grounding conductor to other parts of the system. If bonding occurred at multiple disconnects, it could create parallel paths and circulating currents, energize enclosures, and compromise safety. So, the first disconnecting means is indeed the permissible location for the Neutral-to-Ground bond.
