Backstopping Change Over Panel (BACOP) is best described as which of the following?

• A. A low voltage panel that monitors power distribution from LV switchgear to the Power Distribution Cabinets (PDCs), and from the PDCs out to each rack location.
• B. A monitoring system for all critical mechanical equipment in electrical rooms.
• C. A detailed list of all materials used on the project.
• D. A record of commissioning issues.

Answer: (A)

The main idea is power distribution control and changeover for critical loads. A BACOP is a low‑voltage panel that sits in the path from LV switchgear to the Power Distribution Cabinets and then out to each rack location, overseeing and coordinating the distribution of power and the changeover between sources as needed. This captures its role in monitoring and ensuring continuity of power to the racks by managing how power is fed from switchgear through PDCs to the loads.

The other descriptions don’t fit because they refer to systems outside this distribution and control function: a monitoring system for mechanical equipment, a materials list, or a record of commissioning issues.
