What is the maximum voltage that a neutral potential should not exceed?

The maximum voltage that a neutral potential should not exceed is often set at 10 volts. This standard is crucial because exceeding this voltage can present safety risks and potential electrical shock hazards.

In electrical systems, especially in residential and commercial buildings, the neutral wire is intended to carry current back to the source and is typically at or near ground potential. When the voltage on the neutral exceeds the acceptable level, it can indicate a problem such as improper bonding or grounding, leading to voltage imbalances that could be dangerous.

Maintaining the neutral voltage at or below 10 volts helps ensure the safety and reliability of electrical systems, minimizing risk of electrical shock to individuals and preventing potential equipment damage. This threshold is a common guideline in many electrical codes and standards to protect both people and property.
