Disconnects, through which current normally flows, must remain ______ at all times.

Disconnects, through which current normally flows, must remain ______ at all times.

• A. Closed
• B. Open
• C. Locked
• D. Ready

Answer: (A)

When current is expected to flow through a section of the system, the disconnects in that path stay in the closed position so the electrical circuit remains complete and power can be delivered to the equipment. Opening a disconnect would interrupt that current, causing an outage and potentially unsafe conditions if the work isn’t planned and controlled. They’re opened only to de-energize for maintenance, with lockout procedures used to prevent re-energizing. The other terms don’t describe the normal operating state: being open stops current, and locking or a state like “ready” isn’t the standard position for the normal operation of a disconnect.
