What You’ll Need
Before you begin replacing a circuit breaker, you’ll need to make sure you have everything you need. The necessary items depend on the situation and the type of circuit breaker you are replacing. That being said, here are some basic tools and supplies you’ll need for this task:
– Circuit Breaker Tester: This is an essential tool for any homeowner who needs to know how to replace a circuit breaker. It allows you to see whether or not the circuit breaker is faulty and needs to be replaced.
– Wrench: You’ll need a wrench to remove the cover panel of the circuit breaker panel.
– Screwdriver: A screwdriver is helpful for removing the faulty circuit breaker and connecting the new breaker.
– Safety Goggles: You don’t want tiny fragments of metal or dust entering your eyes while you’re working. Safety goggles can help prevent this from happening.
– Gloves: They can protect your hands from being cut while you’re removing the faulty circuit breaker.
Step 1: Turn Off the Power
The first and most important step in replacing a circuit breaker is to turn off the main power source to the home. You want to make absolutely certain that the current inside the wires is cut off so you don’t suffer a shock while working. If you smell burning or see sparks or smoke anywhere in or around the house, you must shut off the power at the source before doing anything else. This could be anything from faulty wiring to a faulty outlet or switch. It’s better to be safe than sorry.
Step 2: Remove the Cover
Once the power is off, you can move on to the next step: Removing the cover from the faulty circuit breaker. The cover is usually held in place with a screw or two, and is usually located on the front of the breaker. Be careful when you remove it not to touch the live parts inside. After removing the cover, you should be able to see where the circuit breaker is connected to the wires that lead to the rest of the house. A circuit breaker is simply a switch that turns off the power to a portion of the house if something goes wrong. It is usually connected to the wires with either wire nuts or crimp connectors.
Step 3: Mark the Wires
Before you begin removing the faulty circuit breaker, it’s a good idea to mark the wires so you know which one goes where. This makes the rest of the process that much easier and leaves you with less room for error. There are two methods for marking the wires:
The first is to use a volt tester to determine which wires are live and which are neutral. The second is to use a permanent marker to write what each wire is connected to and where it goes.
Using the volt tester is the best option if you have the necessary experience with electricity to know what you’re doing; marking the wires with a permanent marker is best if you’re a novice.
Step 4: Identify Which Circuit Breaker Is Faulty
Now that you’ve marked the wires, you can use the circuit tester to determine where the problem is. Simply attach the two wires to the circuit tester and observe which light turns on. If the light turns on and stays on, then the circuit is still live and faulty. If the light turns on and instantly turns off, then the circuit has been deactivated and is safe to operate. With this in mind, you can proceed to the next step.
Step 5: Remove The Old Circuit Breaker
Now that you’ve determined which circuit breaker is faulty, you can remove it from the electrical system. This can be done by simply unscrewing the wire connections from the circuit breaker and pulling out the faulty breaker from its place. Be careful when removing the circuit breaker, as you can still be shocked by the current that is still flowing through the wires.
Step 6: Reconnect the Wires to the new breaker and Cover
Now that you’ve removed the faulty circuit breaker, you can connect the wires to the new circuit breaker. You’ll want to make sure that you follow the same pattern as before, connecting each wire to the corresponding terminal. Once again, be careful not to touch the live wires and wear rubber gloves to avoid an electric shock.
Step 7: Install the new circuit breaker
Now that the connections have been made, you can install the new circuit breaker in its rightful spot. You’ll want to make sure that the wiring corresponds with the correct terminal. If you’re installing a new circuit breaker, then you’ll want to take care to follow the instructions provided by the manufacturer.
Replace the cover panel and turn the main switch on
Once the connections have been made, the next step is to install the cover panel on the new circuit breaker.
This is done to protect the live wires and make it more convenient to access the system.
Once the cover has been installed, you can turn the main switch on to ensure that the new circuit breaker is operating and the wiring is correct. If everything is working correctly, then you’ve successfully replaced the faulty circuit breaker. And if not, then you may want to consult a professional.
Can I replace a circuit breaker myself?
From this guide, it is crystal clear that you can replace the circuit breaker by yourself. All you need are a few tools and basic knowledge of electronics.
However, it is always a good idea to hire an electrician for the task if you are not familiar with the circuit breaker.
Safety tips to use when replacing a circuit breaker
You would obviously want to be safe when doing the circuit breaker replacement. Here are a few tips that will keep you safe during the job:
-Wear safety clothing: You should dress in protective clothing such as gloves, goggles, and a mask to avoid any electrical shock.
-Be careful when handling wires: The wires are live and you can get an electric shock if you touch them.
-Never work alone: Always work with someone else and keep in constant communication to avoid any injuries.
-Check the circuit breaker regularly: It is recommended that you check the circuit breaker once a month to ensure that it is operating properly.
-Follow the instructions from the manufacturer: When replacing the circuit breaker, you should follow the instructions from the manufacturer.
-Keep children away: If you have children in your home, it is essential to keep them away from the area where you are working on.
-If you smell a burning odor: If you smell something burning or if there is visible smoke, immediately cut off the power and call an electrician.
How can I know that I need to replace my circuit breaker?
There are various signs that it is time to replace your old circuit breaker with a new one. These signs include:
-Constant tripping: If your circuit breaker trips frequently, it may be time for you to replace it with a new one.
-Frequent power outages: If there is a consistent power outage in your home, it may be time for you to get a new breaker.
-Old and worn out: Circuit breakers are designed to last for quite some time. However, if yours is old and worn out, it is definitely time to get a new one.
-Overloaded: You can tell if your circuit breaker is overloaded by looking at the lights on the panel or reading the manual that comes with it. If you notice that the lights on your panel are constantly on or blinking even when there are no appliances plugged in or turned on, then you will need to replace your old circuit breaker with a new one.
If there’s one thing we hope you take away from this article, it’s that you can easily replace your circuit breaker. Just follow the instructions that we have outlined and their safety procedures.
