Which term describes two or more circuits sharing the same neutral conductor and having a common point?

• A. Common
• B. Ground
• C. Neutral
• D. Bus

Answer: (A)

When two or more circuits share the same neutral conductor and connect at a single point, that arrangement is described as a common connection. The shared neutral creates a single return path for multiple circuits, so the circuits are effectively linked through that common point. This is typical in a multi-wire branch circuit, where two hot legs share one neutral and are tied together at the panel to ensure they can be de-energized together. Ground, neutral, and bus describe components or functions, but they don’t capture the idea of multiple circuits sharing a single neutral and tying together at one point as clearly as the term “common.”
