What should be done with the accessible portion of abandoned supply circuits in an IT equipment room?

1. Leave as is

2. Remove it

3. Cover it

4. Contain it in a raceway

The correct answer is: Contain it in a raceway

When dealing with the accessible portion of abandoned supply circuits in an IT equipment room, containing it in a raceway is the best practice. This approach ensures that any unused circuits that are still present do not pose a safety hazard. A raceway provides a protective pathway for the conductors, preventing accidental contact and reducing the potential for electrical shorts or other safety issues. By containing abandoned circuits in a raceway, compliance with electrical codes and regulations is also maintained. It helps in organizing the space, reducing clutter, and ensuring that any future maintenance or upgrades to existing systems can be performed without interference from abandoned equipment. Leaving the circuits as they are, removing them completely, or simply covering them do not offer the same level of safety and compliance. These other options could lead to confusion or accidental engagement with those circuits, posing risks to personnel and equipment in the IT environment.
