Prep & safety

• Turn off the main power supply before inspecting the electrical panel.
• Ensure all devices on the affected circuit are unplugged.
• Wear insulated gloves and safety goggles for protection.
• Use a dry cloth to clean the electrical panel before inspection.

Step-by-step troubleshooting

1. Identify the affected circuit
   Do: Check which breaker is tripped and locate the circuit it controls.
   Observe: Breaker is in the 'off' position or in the middle.
   Means: This is the circuit causing the issue.
   Next: Step 2
2. Reset the breaker
   Do: Push the breaker fully to the 'off' position, then back to 'on'.
   Observe: Breaker stays in the 'on' position.
   Means: Breaker was tripped due to a temporary overload.
   Next: Step 3
3. Check for overloaded circuits
   Do: Unplug all devices on the affected circuit and reset the breaker.
   Observe: Breaker remains on without tripping.
   Means: Overloaded circuit was the cause.
   Next: Step 4
4. Test individual appliances
   Do: Plug in one appliance at a time and observe the breaker.
   Observe: Breaker trips when a specific appliance is used.
   Means: Faulty appliance is causing the issue.
   Next: Step 5
5. Inspect wiring and outlets
   Do: Check for damaged wires, loose connections, or signs of burning.
   Observe: Visible damage or burning smell.
   Means: Wiring issue is causing the tripping.
   Next: Step 6
6. Test the breaker
   Do: Use a multimeter to test the breaker for continuity.
   Observe: No continuity or inconsistent readings.
   Means: Breaker is faulty and needs replacement.
   Next: Step 7
7. Check for ground faults
   Do: Use a circuit breaker finder to detect ground faults.
   Observe: Device detects a ground fault in the circuit.
   Means: Ground fault is causing the breaker to trip.
   Next: Step 8
8. Consult a professional
   Do: If the issue persists, contact a licensed electrician.
   Observe: No obvious cause is found.
   Means: Professional inspection is needed.
   Next: Finish

Common causes

Parts you might need

When replacing parts, ensure they match the specifications of the original components.

• Circuit breaker: match amperage and type (standard, GFCI, AFCI)
• Wire connectors: match wire gauge and material (copper or aluminum)
• Wiring: match gauge and insulation type to the existing wiring
• GFCI outlet: match voltage and amperage of the circuit
• Appliance: match model and power requirements to the original device

Always refer to the electrical panel label and appliance manuals for correct specifications.

When to call a professional

• Breaker trips immediately after resetting with no devices connected.
• You detect a burning smell or visible damage in the electrical panel.
• Testing reveals ground faults but you cannot locate the source.
• You are unsure about handling electrical components safely.
• The issue persists after checking all possible causes.
