You are NOT allowed to recondition equipment with ground-fault circuit-interrupters providing protection for personnel.

• A. Yes
• B. No
• C. Only with manufacturer approval
• D. Only for non-personnel devices

Answer: (B)

Ground-fault protection for personnel is a safety feature that must remain intact and correctly calibrated. Reconditioning such equipment—opening it up, repairing components, or altering wiring—can disturb the sensing circuit or calibration, potentially defeating the protection or voiding the listing. Because the protective function is specifically for safeguarding people, you should not recondition equipment that includes a GFCI for personnel protection. If the unit is faulty, replace it or have it serviced by the manufacturer (and re-test to ensure proper operation). Manufacturer approval does not override the need to maintain the device's listed safety protections, and the protection is not intended for non-personnel devices.
