Is the neutral conductor of a 2-wire, single-phase circuit supplying a household refrigerator considered a current-carrying conductor?

In a 2-wire, single-phase circuit supplying a household refrigerator, the neutral conductor is indeed considered a current-carrying conductor. This is because, in a typical residential electrical system, the neutral wire serves as the return path for the current that flows to the appliance.

When the refrigerator operates, it draws current through the hot wire to power its motor and other components. The same amount of current must then return back through the neutral conductor. Consequently, the neutral wire carries the return current, thus classifying it as a current-carrying conductor.

Understanding this concept is essential for projects involving electrical installations, as it determines how wiring is configured and must adhere to electrical codes, ensuring safety and compliance with regulations.
