Can a primary or secondary neutral on an energized circuit be opened?

The statement that a primary or secondary neutral on an energized circuit should never be opened under any circumstances is based on the critical function that neutral wires perform in electrical systems. The neutral serves as a return path for current and helps maintain the balance of voltages in a system. Opening a neutral on an energized circuit can lead to several dangerous situations, including the potential for equipment damage, overvoltage conditions, or even safety hazards such as electrical shock or fire.

When a neutral is removed from an energized circuit, this disruption can cause an imbalance that affects the entire circuit and any connected devices, potentially exposing them to higher voltages that can be harmful. Therefore, strict protocols are established to ensure that neutrals remain intact when circuits are energized to protect both equipment and personnel.

Additionally, opening a neutral in any energized circuit without proper verification and precautions disregards safety protocols and standards necessary for working with electricity, leading to hazardous situations. Thus, the unequivocal stance is that this action is prohibited to safeguard both the electrical system and the individuals working on it.
