GFCI protection devices shall be tested ?.

GFCI protection devices shall be tested ?.

• A. In accordance with the manufacturer's instructions
• B. Before each use
• C. Monthly
• D. Annually

Answer: (A)

Testing GFCI protection devices should be done in accordance with the manufacturer's instructions. This matters because different models have different test procedures, indicators, reset steps, and recommended testing intervals. The test function is meant to verify that the sensing circuit will trip properly in a ground-fault condition, but the exact method, timing, and post-trip actions are defined by the device’s design. Following the manufacturer’s guidance ensures you use the correct test approach for that specific device and maintain proper protection and compliance. While some workplaces or codes may suggest monthly or other intervals for certain equipment, the universal requirement is to follow the manufacturer's instructions for testing frequency and procedure.
