Master Electrician Practice Exam

What is the requirement for accessible portions of abandoned supply circuits in IT equipment rooms?

1. They must be left in place

2. They should be removed if not in a raceway

3. They can be covered with insulation

4. They must be tagged for removal

The correct answer is: They should be removed if not in a raceway

The correct requirement for accessible portions of abandoned supply circuits in IT equipment rooms is that they should be removed if not in a raceway. This requirement is grounded in safety and code compliance. When abandoned circuits are accessible and not contained within a raceway, they pose potential hazards, such as creating clutter, confusion during maintenance, and potential electrical safety risks if someone inadvertently interacts with them. By removing these circuits, it ensures that there is a clearer operational environment in the IT equipment room, which is critical for both safety and efficiency. Furthermore, in many electrical codes and standards, there is an emphasis on minimizing hazards and ensuring that systems are organized and maintainable. Leaving abandoned circuits in place, covering them with insulation, or simply tagging them does not adequately address the safety issues that can arise in active workspaces. Therefore, the requirement to remove such circuits aligns with best practices in electrical safety and effective facility management.
