Which statement does NOT describe objectionable current?

Which statement does NOT describe objectionable current?

• A. Neutral current on the neutral conductor
• B. Neutral current on the grounding conductor
• C. Neutral current on cable shields
• D. Neutral current on metal conduits

Answer: (A)

Objectionable current refers to unintended or excessive current that can lead to safety hazards, interference, or damage in electrical systems. The statement about neutral current on the neutral conductor does not describe objectionable current because the neutral conductor is designed to carry the return current from the load. In a properly functioning electrical system, the neutral current is expected to flow through the neutral conductor, making it a normal condition. In contrast, objectionable currents can occur when neutral current is present on other conductors, such as the grounding conductor, cable shields, or metal conduits, which are not intended to carry load current. These conditions can lead to potential safety risks, equipment malfunction, or electromagnetic interference. Therefore, identifying that neutral current on the neutral conductor is a standard operational characteristic clarifies why this statement does not describe objectionable current.
