A tripped circuit breaker is a common electrical issue that can disrupt power to your home or business. If you’re facing this problem with a Square D circuit breaker, don’t worry! Resetting it is a simple and straightforward process that you can handle yourself. In this comprehensive guide, we’ll provide step-by-step instructions and helpful tips to ensure a safe and successful reset.
Identifying the Tripped Circuit Breaker
Before resetting, it’s essential to identify the tripped circuit breaker. Look for the panel where your circuit breakers are located. It’s usually a metal box in your basement, garage, or utility room.
- Examine the circuit breakers: Each circuit breaker has an indicator that shows its status. A tripped circuit breaker will have its handle in the middle position, between “On” and “Off.”
Safety Precautions
- Turn off the main breaker: Before working on any electrical components, always turn off the main breaker to cut off power to the entire panel.
- Use insulated tools: Wear rubber gloves and use insulated tools to avoid electrical shocks.
- Check for loose connections: Before resetting, check for any loose wires or connections. Ensure they are securely tightened.
Step-by-Step Reset Instructions
1. Locate the tripped breaker: Identify the circuit breaker that has its handle in the middle position.
2. Turn the breaker off: Push the handle all the way to the “Off” position.
3. Wait a few minutes: Allow a few minutes for the circuit to cool down. This will prevent arcing when you reset it.
4. Turn the breaker on: Push the handle all the way to the “On” position.
Troubleshooting Tips
- If the breaker trips again: If the circuit breaker trips again after resetting, it could indicate an underlying electrical problem. Contact a qualified electrician for further diagnosis and repair.
- If the breaker won’t reset: If you can’t reset the circuit breaker, it may be faulty. Replace it with a new one of the same amperage rating.
- If multiple breakers trip: If several circuit breakers trip simultaneously, it could be a sign of an overloaded circuit or a ground fault. Unplug unnecessary appliances and contact an electrician.

Answers to Your Questions
Q: What causes a circuit breaker to trip?
A: Circuit breakers trip when the electrical current flowing through them exceeds their rated capacity. Overloaded circuits, short circuits, and ground faults are common causes.
Q: How often should I reset my circuit breakers?
A: Circuit breakers should only be reset when they trip. Regular resetting is not necessary and can damage the breaker.
Q: What should I do if my circuit breaker keeps tripping?
A: If a circuit breaker trips repeatedly, it could indicate an underlying electrical problem. Contact an electrician to diagnose and repair the issue.
Q: Can I reset a circuit breaker that has been damaged?
A: No. A damaged circuit breaker should be replaced immediately to prevent electrical hazards.
Q: What is the difference between a 15-amp and a 20-amp circuit breaker?
A: A 15-amp circuit breaker is rated for 15 amps of current, while a 20-amp circuit breaker is rated for 20 amps. The higher the amperage rating, the more current the breaker can handle before tripping.
