During a troubleshooting job, the homeowner reported intermittent power loss. I inspected the circuit breakers and checked all outlet wiring for loose connections. Using a multimeter, I identified a faulty GFCI outlet causing the issue. I replaced the GFCI and rechecked the system. After confirming the circuits were stable and the outlets functioning correctly, I explained how to monitor for potential future issues. The home’s electrical system is now working reliably.
