Breaker Keeps Going Off

Quick answer

A breaker that keeps tripping is usually caused by an overload, short circuit, or ground fault. Turn off the affected circuit, unplug devices, and reset the breaker. If it trips again, consult an electrician.

Confirm the symptom

• Breaker trips repeatedly after being reset
• Breaker trips when using specific appliances
• Breaker trips without any devices plugged in
• Breaker feels warm or smells burnt

Tools and prep

• Non-contact voltage tester — Detects live wires without touching them
• Multimeter — Measures voltage and continuity for troubleshooting
• Wire stripper — Strips insulation from wires without damaging conductors
• Needle-nose pliers
• Flashlight

Prep & safety

• Turn off the main power supply before inspecting the electrical panel
• Wear insulated gloves and safety goggles
• Ensure all appliances and devices are unplugged

Step-by-step troubleshooting

1. Identify the affected circuit
   Do: Locate the breaker that keeps tripping and note which outlets or lights are on that circuit
   Observe: Breaker is in the 'off' position or between 'on' and 'off'
   Means: This confirms the correct breaker is being addressed
   Next: Unplug all devices on the affected circuit
2. Unplug devices
   Do: Unplug all appliances and devices connected to the affected circuit
   Observe: Breaker stays in the 'on' position
   Means: The circuit is no longer overloaded
   Next: Reset the breaker
3. Reset the breaker
   Do: Switch the breaker fully to 'off' and then back to 'on'
   Observe: Breaker stays 'on' without tripping
   Means: The issue may be resolved temporarily
   Next: Plug in devices one at a time
4. Test devices
   Do: Plug in devices one by one and observe the breaker
   Observe: Breaker trips when a specific device is plugged in
   Means: The device is likely causing the overload or short
   Next: Replace or repair the faulty device
5. Inspect wiring
   Do: Check for damaged or frayed wires in outlets and switches on the affected circuit
   Observe: Visible damage to wires or connections
   Means: Damaged wiring can cause shorts or ground faults
   Next: Repair or replace damaged wiring
6. Test with a multimeter
   Do: Use a multimeter to check for continuity and proper voltage in the circuit
   Observe: Abnormal readings indicate a wiring issue
   Means: The circuit has a fault that needs professional attention
   Next: Call a licensed electrician

Common causes

Parts you might need

When replacing parts, ensure compatibility with your electrical system and the specific requirements of the affected circuit.

• Circuit breaker: match amperage rating and type (standard, GFCI, AFCI)
• Wires: match gauge (AWG) and insulation type
• Wire connectors: match wire size and number of wires
• GFCI outlet: match voltage and amperage of the circuit
• Appliances: match power requirements and circuit capacity

Always consult the manufacturer's specifications for the correct replacement parts.

When to call a professional

• Breaker trips immediately after replacement
• You detect a burning smell or visible damage in the panel
• The issue persists after unplugging all devices
• You're unsure about the cause or how to fix it safely
• The electrical panel is old or shows signs of wear
