Have you ever walked into your garage late at night and noticed a strange flickering or smelled something burning? You trace the source of the smell to a junction box and lift the lid to find burnt and charred electrical wiring inside. Your heart sinks as you realize you now have an electrical fire hazard on your hands that needs immediate addressing.
Electrical wiring that has burnt or melted poses serious safety issues that should not be ignored. Left unchecked, damaged wiring could lead to outlet or light fixture failures, circuit breaker trips, or even spark an electrical fire.
In this blog post, I will share several effective methods for how to fix burnt electrical wires that have become compromised through burning or melting so you can safely resolve the issue and rest easy knowing your home’s electrical system is back in good working order.
What Will You Need?
Before getting started, there are several tools and materials you will need in order to fix burnt electrical wires safely. These include:
- Wire cutters/strippers
- Electrical tape
- Multimeter (optional)
- Heat shrink tubing
- Soldering iron/solder (optional)
Once you have gathered these materials, you will be ready to begin fixing the burnt wires.
10 Easy Steps on How to Fix Burnt Electrical Wires
Step 1. Turn Off the Electricity
The first step to fixing burnt electrical wires is to turn off the electricity. This should be done by turning off the power at the circuit breaker or fuse box. Once the energy has been turned off, you should use a voltage tester to ensure that all of the wires are entirely disconnected from any source of electricity.
Step 2. Inspect for Damage
Once you have turned off the power, it’s time to inspect for damage. You should look for signs of charring or burning on the insulation around the wires, as well as any discoloration or melting of plastic parts. If you find any damage, it’s important to replace those components with new ones before proceeding any further with repairs.
Step 3. Replace Damaged Components
If you find that some components are damaged beyond repair, they must be replaced with new ones before attempting to fix the burnt electrical wires. It is essential to ensure that all of your replacement parts are rated for use in your particular application and that they meet all safety standards and codes. Additionally, you should always wear protective gear when working with electricity and follow all safety instructions from local building codes or fire department regulations.
Step 4. Strip Back the Insulation
After ensuring you have all the necessary replacement components and all safety measures, the next step in fixing burnt electrical wires is to strip back the insulation on the burnt wires.
To do this, take your wire cutters/strippers and carefully strip away about an inch of insulation from each end of the wire, exposing the raw metal wire underneath. Be cautious not to cut into the wire, which can cause more damage. Once the wire is exposed, check for any discoloration or damage. You can proceed with the repair if the wire looks healthy and is not discolored or brittle. If the wire does show signs of damage, it would be best to replace it entirely.
Step 5. Splice the Wires
If the wire is still in good condition, the next step is to splice the wires together. This is done by twisting the stripped ends of the two wires together. Ensure the cables are firmly twisted and there is good metal-to-metal contact for adequate current flow. This is a critical step on how to fix burnt electrical wires.
Step 6. Apply Heat Shrink Tubing
After splicing the wires together, it’s time to insulate the connection to prevent any future electrical shorts or fires. Cut a piece of heat shrink tubing that’s long enough to cover the spliced area and a bit of the insulation on both sides. Slide the tubing onto the wire, then position it over the splice. Use a heat gun or lighter to shrink the tubing until it tightly covers the splice. This creates a robust and fire-resistant barrier around the repaired area, contributing to the safety and longevity of your electrical wiring.
Step 7. Test the Repair
Once you have finished insulating the spliced wires with heat shrink tubing, it’s important to test the repair before restoring power. If you have a multimeter, use it to check for continuity in the repaired wire. It should show a low resistance (near zero ohms) if the splice is good. If the resistance is high, the splice may have a problem, and you should re-do the previous steps. If you don’t have a multimeter, visually inspect the repair to ensure no loose wires and the heat shrink tubing covers the splice entirely.
Step 8. Restore Power
After you have successfully tested the repair, the final step in fixing burnt electrical wires is to restore power. Go back to the circuit breaker or fuse box and turn the power around for the circuit you were working on. Once the power is restored, check the operation of the device or circuit connected to the repaired wire. If everything works correctly, your repair is successful. If the circuit is still not functioning correctly, there may be other issues, and consulting a professional electrician is recommended.
Step 9. Regular Maintenance and Inspection
To prevent future instances of burnt electrical wires, it’s essential to maintain regular inspection of your electrical system. Look out for signs of wear and tear, like fraying wires, discolored wall outlets, or frequent tripping of circuit breakers. Regular maintenance helps identify potential issues early and allows for timely intervention, thus ensuring the safety and efficiency of your electrical system. A professional electrician can conduct regular inspections and maintenance if you are not comfortable doing it yourself.
Step 10. Hire a Professional
Lastly, if at any point during this process, you feel unsure or uncomfortable, consider hiring a professional electrician. Fixing burnt electrical wires can be a complex task, and doing it incorrectly can lead to serious consequences, including the risk of electrical fires.
Professional electricians have the necessary skills, experience, and tools to safely and effectively repair burnt wires. They can also identify and address any underlying issues that might have caused the wires to burn in the first place. Remember, safety should always be your top priority when dealing with electricity.
By following these steps, you can successfully fix burnt electrical wires and ensure the safety and efficiency of your electrical system.
5 Additional Tips and Tricks
- Identify the Problem Early: The first step in fixing burnt electrical wires is early detection. Regularly check your wires for any signs of overheating such as discoloration, a burning smell, or fizzing sounds.
- Ensure Safety First: Before attempting to fix burnt wires, always turn off the circuit breaker to avoid electric shock. Wear insulated gloves and use insulated tools for added safety.
- Use Quality Replacement Wires: When replacing burnt wires, choose high-quality, UL-listed wires rated for your circuit’s current load. This will help prevent future overheating and burning.
- Proper Wire Connections: Ensure all wire connections are secure and insulated. Loose connections can cause arcing, leading to overheating and burnt wires.
- Try Surge Protectors: If your wires are prone to burning due to power surges, consider investing in surge protectors. These devices help regulate the electrical current and can help prevent damage to your electrical system.
With these additional tips and tricks, you can ensure that your electrical wires stay in good condition and prevent the need for frequent repairs.
5 Things You Should Avoid
- Avoid DIY if Unqualified: Electrical work is complex and dangerous. If you’re not confident or qualified, avoid trying to fix burnt electrical wires by yourself, as it can lead to further damage or potential hazards.
- Don’t Neglect Regular Checks: Ignoring regular checks of your wiring system can lead to unnoticed problems escalating into serious issues, like burnt electrical wires.
- Never Use Mismatched Wire Sizes: Using wires that aren’t the correct size for your circuit can lead to overheating and burning. Always ensure you are using the accurate wire gauge for your specific needs.
- Don’t Skimp on Quality: Opting for cheaper, lower-quality wires may seem cost-effective in the short term, but it can lead to more frequent burnouts and repairs in the long run.
- Avoid Overloading Circuits: Plugging too many devices into a single circuit can cause overheating and burn the wires. To prevent this, be mindful of the load your circuits are handling.
By avoiding these common mistakes, you can keep your electrical system in good condition and reduce the risk of burnt wires.
