Tracing Wires Hidden Inside Your Walls! [DIY Guide For Beginners!]

Facing electrical issues can be frustrating, especially if you want a chilly Sunday afternoon. A certain disruption may make you feel the need to set things right.

You can explore the best way to trace wires hidden inside your walls.

The process involves locating the junction boxes by turning off the main power. Then you will be testing the wires using Klein tools for grouping and labeling. By doing that, you can follow and trace the line connections. This is to connect black and white lines accordingly.

By following six simple steps, you can ensure a good power output. This is to make you feel satisfied with your devices running at their best.

How To Deal With The Wires Hidden Inside The Walls

The problem starts when electrical malfunctions are happening in your house. It can be so that your electrical appliances are not working properly. A close inspection reveals a scattered wiring system that is coming out of the house outlets.

This is why understanding the best way to trace wires hidden inside your walls is vital. This article is a demonstration that includes a drywall scenario.

The drywall is connected to 3 junction boxes. This includes a switch, a light fixture, and a power outlet. This is similar to the wiring pole switch to light and power outlet on the same circuit.

You will need Klein tools to perform the actions that will be indicated. This is in a six steps scenario. In this context, you shall be learning how to trace electrical wires to breakers.

Step 1: Turn Off The Power From The Circuit Breaker

While inspecting the outlets you may have taken off the switches from the junction box. As you have figured out the cables are scattered, and you don’t know how to fix this. The following steps will let you do the job.

As suggested before, to fix the problem, tracing the lines is important. This is by detecting the signal.

You can use detect electrical wires in the walls app. But to feel perfection, you need some tools for better results.

This is why using the cable tracer tool (also called a probe) is important. You are going to need this throughout the other steps.

In the first step, however, you are going to turn off the circuit breaker. This is to avoid any short-circuiting issue which can injure you. You need to fix the cables connecting to the electrical outlets.

The point is to ensure that the cables are connected evenly with the 3 outlets. The 3 outlets are represented by junction boxes. Through these boxes, the cables pass and connect.

Step 2: Locate The Junction Boxes

In the 2nd step, you have to locate the junction boxes. In the drywall demonstration scene, the three outlets are placed in a triangular notion.

This is to ensure that the right cable line is connected. This is through the 3 main power lines, demonstrated in junction boxes.

You are going to use a wall wire tracer. This is to figure out how much electrical power the lines are conducting.

The 14/2 or 12/2 gauges of wires should be connected through hot, neutral, and ground lines. The hot and ground lines are represented by black and white cables for even electric distribution. This means the white and black cables should connect throughout the 3 outlets.

By using Klein tools you are going to trace and outline the wires. This is in terms where the lines are coming across to cause problems. By doing so, you can separate the wires to fit in accordingly.

Step 3: Test The Wires With Klein Tools

The Klein tools are induced with two power tools. One is the toner and the other is the probe. The toner comes with two alligator clips that are connected with the toner. The two clips are red and black in color.

These clips will help to outline the different lines of the cables for proper connection. This is to ensure how to trace a broken electrical wire in the wall.

The tracer ( or the probe ) is therefore used to demonstrate the noise function. By understanding the noise the lines are making, you can align the wires accordingly.

If the connections are scattered, you will hear a loud noise. This means you need to group or label the wires accordingly.

You must know how to test home electrical wires with a multimeter. This is to make this step take root with the Klein tools.

To work sufficiently, you have to leave out the neutral lines. This is because we are going to be working with the hot and ground lines. This is where the black and white cables are going to be connected.

Attach the black alligator clip with the black line. This should be followed by the attachment of the red alligator clip. This is with the white line. After that, you will turn on the toner to see the wattage levels.

Step 4: Label And Group The Wires Separately

The idea is to secure an even electric distribution. With the help of the toner, you can secure it to 800 watts or 1000 watts. This means all the electrical lines must have the same tone.

You can do that when the black and white connections are wired accordingly. You may want to know how to trace a wire without power. You would be doing that by labeling the circuit breaker.

Be aware of the national code of conduct. This is if you want to wire electrical tapes around the outlets.

You are going to label and group the black and white lines. Using the toner, you are going to understand how to connect the pairing. This is in the 3 outlets where the high and low noises will be monitored.

Step 5: Follow And Trace The Line Connections

The labeling job is done here for the next process to take root. You will be using the toner to follow the noise over the drywall.

By following the trails, you will know how the different wires have moved. This is to connect the outlets.

By now you have known how to trace an electrical wire in a house. You are going to fix the loud noise scene by straightening out the cables. This is to make sure that the black and white lines are not touching.

Step 6: Remove The Drywall To See If The Connections Are In Order

In the drywall demonstration scene, you have to remove it. This is to see if the cables are connected properly to the three junction boxes. In the house scene, this means 3 outlets.

As you have labeled the black and white connections, the pairing should be perfect. This means you should be knowing how to check the electrical wiring in the home.

There can be hot outlet issues with improper pairing. This can also be followed by unnecessary wires hanging around. All you have to do is cut and remove the unwanted neutral lines.

Once you have done the wiring properly, the uneven electric power will be avoided. You can therefore count on no short-circuiting happening in your house.

Run your appliances to see how they are performing. If the charging system is doing a favorable job, you have done well!

To complete the entire job successfully, you will need a handful of tools.

FAQs

How do you find hidden wires inside the wall?

You can find the connecting wires inside the wall by using a probe tool. The hot signals can help you line up the wires by taping or marking them. You can do this on the wall to the circuits.

How do I know which gauges of wires to use?

Typically a 15 amp circuit around the house is wired with 14/2 gauges. If you want to get new cables, you have to buy the 14/2 wires. This is listed in the product table above.

What to do if some of the electrical wires are broken?

A multimeter or a Klein tool toner will help you determine how much power there is. If the power goes less than 800 watts, the wires are broken. You have to rewire the entire system by using new cables.

Conclusion

You are in luck for tracing wires hidden inside your walls. You should be finding success after reading the whole article.

Hope you have a good time all around.
