Breaker Keeps Tripping: How to Fix

Quick answer

Turn off the tripped breaker and unplug devices on that circuit. Reset the breaker. If it trips again, check for short circuits, overloaded circuits, or faulty appliances. Call an electrician if the problem persists.

Confirm the symptom

• Circuit breaker repeatedly trips without a clear reason
• Breaker trips after plugging in or using certain appliances
• Breaker resets but trips again shortly after

Tools and prep

• Voltage tester
• Multimeter
• Wire stripper
• Screwdrivers
• Infrared thermometer
• Flashlight

Prep & safety

• Turn off the main power at the service panel before inspecting wiring.
• Wear insulated gloves and safety glasses.
• Ensure all devices on the affected circuit are unplugged.
• Check the circuit breaker panel for any visible damage or burning smells.

Step-by-step troubleshooting

1. Identify the Circuit
   Do: Determine which breaker is tripping and what devices/appliances are on that circuit.
   Observe: Breaker is in the 'off' position or between on/off.
   Means: Breaker has tripped due to an overload or fault.
   Next: Unplug all devices on that circuit and reset the breaker.
2. Reset the Breaker
   Do: Turn the tripped breaker fully to 'off', then back to 'on'.
   Observe: Breaker stays in the 'on' position without tripping.
   Means: The issue may be resolved temporarily.
   Next: Plug in devices one at a time to identify the cause.
3. Test for Overload
   Do: Plug in devices gradually and monitor the breaker.
   Observe: Breaker trips again when a specific device is plugged in.
   Means: The device is likely causing the overload or short.
   Next: Remove the device and inspect it for faults.
4. Inspect Wiring and Outlets
   Do: Use a voltage tester and flashlight to check outlets and wiring for damage.
   Observe: Visible damage, burning smell, or sparks.
   Means: There is a wiring issue or short circuit.
   Next: Turn off power and consult an electrician.
5. Check for Ground Faults
   Do: Use a multimeter to test for continuity and ground faults in the circuit.
   Observe: Irregular readings or continuity where there shouldn't be.
   Means: There is a ground fault or short in the wiring.
   Next: Consult an electrician for further inspection.
6. Test Appliances
   Do: Test each appliance on the circuit with a multimeter.
   Observe: Appliance shows signs of short or overload when tested.
   Means: The appliance is faulty and needs repair or replacement.
   Next: Replace or repair the faulty appliance.
7. Inspect Breaker
   Do: Check the breaker for signs of wear or damage.
   Observe: Breaker is damaged or not holding in the 'on' position.
   Means: The breaker itself is faulty.
   Next: Replace the breaker with a new one of the same rating.

Common causes

Parts you might need

When replacing parts, ensure compatibility with your electrical system:

• Circuit breaker: match amperage and type (standard, GFCI, AFCI)
• Wire nuts: match wire gauge and number of wires
• Electrical wire: match gauge and insulation type
• GFCI outlet: match voltage and circuit type
• Appliances: match wattage and circuit capacity

Always turn off the main power before replacing any electrical components.

When to call a professional

• Breaker trips repeatedly even after removing all devices.
• You smell burning or see visible damage in the panel.
• You suspect a ground fault or arc fault but cannot locate the source.
• You are unsure about any step or feel unsafe working with electricity.
• The issue involves main service panel or high-voltage circuits.
