Start TroubleshootingCommon Electrical Problems
⚡ No Power / Dead Circuit
Outlet, circuit, or entire panel has no power
• Check breaker position (tripped breakers may appear ON)
• Test outlet with known working device
• Check upstream GFCI devices
• Verify service entrance has power
🔄 Breaker Keeps Tripping
Circuit breaker trips repeatedly after reset
• Identify if overload or short circuit
• Disconnect loads and test circuit
• Check for damaged wiring or connections
• Verify breaker is properly sized
🔌 GFCI Won't Reset
GFCI device trips immediately or won't stay reset
• Disconnect all downstream loads
• Test with no load connected
• Check for ground faults in wiring
• Verify line/load wiring is correct
💡 Lights Flickering
Lights dim, flicker, or change brightness
• Check for loose bulbs and connections
• Identify if problem is one circuit or whole house
• Check for high-draw appliances cycling
• Inspect neutral connections
⚙️ Motor Won't Start
Motor hums, trips overload, or doesn't run
• Check for voltage at motor terminals
• Verify overload heater sizing
• Check for mechanical binding
• Test motor windings with megger
🔥 Burnt Smell / Hot Wires
Burning smell from outlet, panel, or equipment
• DE-ENERGIZE IMMEDIATELY if safe to do so
• Locate source of heat/smell
• Check for loose connections (most common cause)
• Inspect for undersized conductors
Systematic Troubleshooting Method
Gather Information
What happened? When did it start? What changed recently? Interview the customer.
Verify the Problem
Confirm the symptom yourself. Test with your own equipment.
Identify the Circuit
Which circuit? Which breaker? What other loads are on this circuit?
Divide and Conquer
Isolate sections. Disconnect loads. Find where the problem starts/stops.
Test Your Theory
Make one change at a time. Verify fix before moving on.
Repair and Verify
Make the repair. Test the circuit under load. Confirm the problem is resolved.
Essential Test Equipment
Digital Multimeter
Voltage, current, resistance, continuity testing
Non-Contact Voltage Tester
Quick presence of voltage detection
Circuit Tracer
Identify which breaker feeds which outlet
Clamp Meter
Measure current without breaking the circuit
Receptacle Tester
Quick check for common wiring faults
Megohmmeter (Megger)
Insulation resistance testing for motors and cables

"GFCI in the bathroom won't reset. I disconnected everything but it still trips immediately."
"Since it trips with nothing connected, the fault is likely in the wiring or the GFCI itself. Try these steps: 1) Verify you disconnected the LOAD terminals, not just the devices - the wiring going to downstream outlets. 2) Check line/load wiring - reversed connections cause immediate trips. 3) Test with a known-good GFCI. 4) If it still trips, there may be a ground fault in the line-side wiring between the panel and the GFCI."
