How should abandoned boxes be handled according to the code?

Abandoned boxes must be made safe or removed to comply with the National Electrical Code (NEC). This requirement is grounded in the principles of safety and functionality within electrical installations. An abandoned box that is left in place can create a range of problems, including the potential for accidental electrical contact, confusion during future electrical work, or interference with new installations.

By mandating that abandoned boxes be either made safe or removed, the NEC aims to minimize hazards and ensure that the electrical system remains reliable and easily manageable. Making an abandoned box safe might involve disconnecting power to it and ensuring that the box is either filled and sealed properly or removed altogether. This approach emphasizes the importance of maintaining clear and safe pathways for electrical conductors and ensuring that all components within an electrical system serve a purpose and comply with safety standards.
