How should you respond if a GFCI trips during setup?

• A. Ignore the trip and continue.
• B. Replace the GFCI with a standard outlet.
• C. Reset without checking cause.
• D. Identify the cause, reset if appropriate, and ensure it and load are safe; investigate for ground fault or moisture.

Answer: (D)

When a GFCI trips, it’s signaling that electricity is leaking somewhere on the circuit or there’s moisture/ground fault on or near the load. The right response is to investigate and address the cause before restoring power. Start by unplugging the equipment, inspecting cords, outlets, and any fixtures for damage or moisture, and drying or repairing as needed. Check for sources of leakage such as wet floors, puddles, or damp stage areas, and ensure connections are clean and dry. If you find a fault or moisture, fix it and then reset the GFCI once the area and gear are confirmed safe. If the fault isn’t obvious or the GFCI keeps tripping, don’t reset—tag the circuit and get supervision. This approach preserves the protective function of the GFCI and reduces the risk of shock or further damage.
