Which task is performed as part of monthly maintenance of equipment?

• A. Check power cords for fraying or wear
• B. Recalibration
• C. Replace fuses
• D. Clean exterior surfaces

Answer: (A)

Safety and reliability come from routine checks of electrical components during monthly maintenance. Inspecting power cords for fraying or wear is essential because damaged insulation or exposed conductors can lead to electric shock, short circuits, or fires. Catching such wear early prevents dangerous failures and helps ensure the equipment remains safe to operate.

Recalibration, on the other hand, focuses on accuracy of measurements or outputs and is typically scheduled less frequently, such as quarterly or annually, or after repairs. Replacing fuses is a fault-driven task—fuses should be changed if they have blown or if the manufacturer specifies replacement after a fault, not as a regular monthly ritual. Cleaning exterior surfaces is part of general upkeep, but it doesn’t directly address electrical safety or performance in the same preventive way as checking cords.
