Like any other device housed in circuit breaker boxes, a circuit breaker has a limited shelf life. Most circuit breakers last about 30 years, so depending on your home’s age, you may need to replace your circuit breaker at some point.
Fortunately, replacing a circuit breaker is a straightforward process. Read on to learn how to replace a circuit breaker in your circuit breaker box.
Steps for Safe Circuit Breaker Replacement
1. The first step to replace a home circuit breaker is gathering these supplies:
- Rubber-soled shoes and insulated gloves
- A voltage tester
- A rubber surface to stand on while you work
- A new circuit breaker that is the same model as the one you’re removing
- An insulated, battery-powered light source
- Insulated screwdriver, pliers, and wirestrippers
- Cable connectors to attach the new breaker to the panel
Once you have these items, check that the floor around the circuit breaker is completely dry. If it’s damp, do not try to replace the breaker.
2. Next, you should unplug all appliances connected to the circuit you’re about to replace. Then, take these steps to start preparing your breaker for replacement:
- Turn on your light source
- Turn off each circuit breaker
- Shut off the main circuit breaker
- Use the voltage tester to confirm that each circuit breaker is off
3. The next step is unscrewing the circuit panel cover. Make sure the electrical panel does not touch the inside of the main circuit breaker box as you remove it.
4. Now, you’ll remove the old circuit breaker. But before you do, notice its placement so you know how to install the new breaker.
5. Then, you should use your screwdriver to turn the terminal screw until you’ve loosened the wires. Use your pliers to untangle the wires, then remove and dispose of the faulty breaker.
6. Next, replace the new breaker by doing the following:
- Ensure that the new breaker is in the OFF position, then install the new breaker
- Reconnect the wires
- Use your pliers to turn the terminal screw until secure
7. Replace the panel cover, turn on the main breaker, then turn on the rest of the breakers. Use your voltage tester to verify that each breaker has power.
8. Plug in your appliances and confirm that the breaker is powering them
When Should You Replace the Circuit Breakers?
Circuit breakers last about 25-30 years before needing replacement. However, you may need to replace a circuit breaker sooner if it becomes dysfunctional.
First, if your breaker repeatedly trips, it’s showing the first signs of wear and tear. If you try to reset it, but it keeps tripping, it most likely needs replacement.
You should also regularly inspect your panel for signs of decay. Consider replacing your circuit breaker if you see signs of:
- Discoloration
- Rust
- A burning odor
- A burned or blackened area
- Melted or frayed wires
Besides the panel, you may notice other signs that point to a defective circuit breaker. Your lights might flicker or dim, especially whenever you turn on an appliance. You may also see a discolored or burned-looking outlet.
Operating a new appliance may also require you to replace your circuit breaker. Newer appliances demand more amps, which will likely overtax your current model.
Upgrading to Arc Fault Circuit Interrupters
For improved safety, consider replacing older circuit breakers with a arc fault circuit interrupter. AFCIs are designed to prevent electrical fires by detecting and interrupting arc faults, which are unintended electrical discharges that can occur in damaged or deteriorated wires and connections.
Maintenance Tips for Electrical Panels and Circuit Breakers
Regular maintenance of your electrical panel and circuit breakers is crucial for ensuring home safety and extending the lifespan of your equipment. Here are key tips to keep your electrical system functioning optimally:
1. Annual Inspections: Have a qualified electrician inspect your electrical panel annually to identify potential issues like loose connections or signs of wear.
2. Clear Surroundings: Keep the area around the electrical panel clear and accessible. This not only facilitates easy maintenance and emergency access but also prevents overheating by ensuring proper ventilation.
3. Monitor for Overheating: Look for signs of discoloration or melting on circuit breakers and other components, which could indicate overheating.
4. Test Circuit Breakers: Periodically flip circuit breakers on and off to test their functionality. Replace any that do not toggle smoothly.
5. Secure Connections: During inspections, ensure all electrical connections are tightened as loose connections can lead to overheating and fires.
6. Upgrade Outdated Systems: If your panel or breakers are outdated, consider upgrading to modern devices like arc fault circuit interrupters (AFCIs) and ground fault circuit interrupters (GFCIs) for better protection.
7. Label Circuits: Clearly label each circuit in the breaker panel for quick identification during maintenance or emergencies.
8. Seek Professional Help if Needed: If you’re unsure about performing maintenance safely, it’s best to consult a professional electrician.
Adhering to these tips will help maintain the safety and efficiency of your home’s electrical system, preventing hazards and unnecessary expenses.
Frequently Asked Questions (FAQs)
How Do I Know If My Circuit Breaker Is Faulty?
Identifying a faulty circuit breaker is key to maintaining your home’s electrical safety. Common indicators include a frequent tripped breaker, inability to stay reset, signs of physical damage such as burning smells or discoloration, and persistent issues like flickering lights. If you observe any of these symptoms, it might be time to consider a replacement.
What Are the Risks of Replacing a Circuit Breaker Myself?
While replacing a circuit breaker can be straightforward, it does come with risks. Electrical work can be hazardous if not performed correctly, potentially leading to electric shocks, electrical fires, or damaging your home’s electrical system. It is crucial to follow all safety guidelines meticulously and consider hiring a professional, especially if you are not experienced with electrical repairs.
Can I Upgrade My Circuit Breakers for Heavier Electrical Loads?
Upgrading your circuit breakers to handle heavier loads can be necessary when adding new appliances or upgrading existing ones that consume more power. It’s important to consult with a licensed electrician to determine the appropriate breaker size that complies with local electrical codes. Incorrect breaker sizes can pose safety risks.
What Should I Do If the New Circuit Breaker Still Trips?
If your new circuit breaker continues to trip, it could indicate an underlying issue in the circuit, such as overloading, short circuits, or faulty wiring. First, ensure that the load on the breaker is within its capacity. If the issue persists, it’s advisable to consult a professional electrician to diagnose and resolve the problem accurately.
How Do I Troubleshoot Circuit Breaker Switches?
If you’re experiencing issues with your electrical system, checking the circuit breaker switches for any signs of wear or failure is a good first step. Ensure they switch on and off smoothly and stay in the intended position without flickering.
