What must be done to multiple conductors under a single terminal?

When multiple conductors are connected under a single terminal, they must be labeled and marked to ensure clarity and safety. Proper labeling helps anyone working on the electrical system understand which conductor is which, thereby minimizing the risk of mistakes during maintenance or troubleshooting. Accurate identification is crucial in preventing electrical faults, ensuring that the system operates safely and effectively.

In terms of safety and compliance with electrical codes, marking conductors under a terminal contributes to overall system integrity, facilitating both installation and inspection processes. This practice is essential in preventing confusion and ensuring that each conductor can be traced back to its source or purpose.

Other options such as leaving conductors unmarked, connecting them directly without appropriate identification, or merely wrapping them in tape do not provide the necessary information for maintenance or future inspections. These methods do not comply with best practices in electrical work, which emphasize the importance of clear identification and marking of electrical components.
