What to Do with Unused Live Electrical Wires?

Electricity is an integral part of our daily life, especially when powering and lighting household appliances. Your electrical cables can be hazardous for a long time if anyone does not take the necessary precautions. In fact, a question may always go around your mind, what to do with unused live electric wires.

When removing or opening a wall or ceiling, you may find loose electrical cables. Cables may be routed to a disconnected electrical outlet or lamp.

Also, previous users may have hidden wires behind the drywall, a hazardous practice. Let’s find out some safety measures for avoiding the possible hazards with unused live electric cables.

What will happen if you touch a Live Wire?

When you touch the cable, things that happen will depend on whether current can flow. The current flow requires a path for completing the circuit (flow of electrons around the loop). Also, it depends on the amount of current flowing.

See Ohm’s Law, Where, (Source)

I = voltage

R= voltage / resistance (for DC)

Z= Voltage/Impedance (for AC).


However, 12V is so little to produce a prominent current flow through the body, whereas 120VAC is sufficient and may burn out unless you get an electric shock.

The possible injury by both AC and DC is not as significant as any other factor, such as whether current flows within the heart and chest.

Moreover, touching a heated cable when grounding with the other hand, can be more hazardous than touching the ground when standing on anything. The reason behind this is the current rises with one hand through the chest and with the other outward.

On the issue of being able to let go, we have all seen in the movies you can’t let go, presumably, with an adequate current in the body. It swamps any nerve signals that your body might have. In effect, your muscles will fully actuate.

If it is isolated (for example, it stops at anything that obstructs all possible current paths to the origin), the current will not flow, and nothing happens. For this reason, birds with high voltage cables are not electrical.

However, nothing is the ideal insulator. So, you will find enough voltage through which potentially risky currents can pass. Even it is possible to bend in a vacuum, but this is extreme.

What Does It Mean to Terminate a Cable?

When the mediocre computer user studies about computer wires and devices, he or she often analyzes them for the essential elements. The power cable is commonly used in the industry to transfer energy to another place.

Sometimes it can be permanent or temporary. Yet, this is the only thing that can efficiently avoid hazards with unused life electrical wires. But you have to do the job right.

The phrase power cable is extensive and describes many different wires. The cable termination kits are useful for fiber optics plus welding and testing.

Those kits are vital for fiber optic specialist as they make your job easier. You must make sure that you have the equipment, including all the necessary tools. The cable termination kit includes the following tools:

  • Scissors
  • Power tape
  • Tweezers
  • Screwdrivers
  • Pliers

Purpose of the Cable Termination Kits:

Not all, you may also need glasses because you don’t want to hurt your eyes. It is best to be prepared ahead of time to avoid accidents. For safety reasons, plug-in connectors occupy an essential place in the range of electrical components.

However, they make connections touch proof. You may find two parts, called sockets and plugs.

Connect polymer cables to tools such as repairing transformer. They are focused on mechanical and electrical energy and are used for leads, resulting in contact-resistant properties.

How to Terminate Unused Electrical Wires?

To terminate unused electric wires, keep your eyes on the following steps.

Tools and Materials Required:

  • Wire stripper
  • Electrical tape
  • Screwdriver with flat-head
  • Anti-contact voltage tester
  • Wire caps
  • Utility knife
  • A blank wall plate
  • Electrical box

Steps to Follow:

The following are some tips for terminating unused electric wires.

Step 1 (Power Off):

  • Disconnect the electrical circuit by turning off the relevant circuit breaker on the home electrical panel or junction box. To add it safely, run duct tape through each switch involved in this project so that no one, including you, accidentally turns on the switch.
  • In the control box, check all wiring that will work with the voltage regulator. Touch the test catheter with all cables and all components of every cable in the box. The tester has to indicate that there is no voltage. If the voltage is detected, go back to the service panel, turn off the corresponding switch and try to connect again.

Step 2 (Prepare Bare Cable Ends):

  • Using an electrical cable stripper, cut the bare cable ends to the custom cable jacket. Remove the plastic casing from the end of the wires. Ensure you have around 1/2 inch of neat, straight wire at the edge.

Step 3 (Put the Nuts on the Wires):

  • Tighten the plastic nuts on the end of the cables. Utilize the correct size cable nut. Too large wire nuts will not hold them well enough and will fall. Also, too small cable nuts may initially seem the same as they are in the cable, but they can also fall. Then, turn the cable nut clockwise.
  • However, the bare copper grounding cables must not be covered. Likewise, the metal shielded housing of the BX cable that leads to the ground leaving the requirement for an extra ground cable and can be put aside.

Step 4 (Add Duct Tape to Individual Cables):

  • Attach all wire nuts to its corresponding cable with the electrical tape.

Step 5 (Insert the Cables into the Box)

  • Insert the cables following the box. Make sure your assemblage isn’t broken up before moving on to the subsequent step. Any unsealed copper wire can make a short circuit or fire.

Step 6 (Add a Blank Wall Decal to the Box)

  • Connect the blank wall panel to the control box with the supplied screws. You can paint some blank wall plates.
  • If the terminal cables are composed of an active circuit, now it is secure to reestablish power to your channel. If all the terminal wires contain only one complete circuit, the circuit must not be activated.

Final Verdict:

There you have the entire scenario “What to do with unused live electrical wires.” Proper cable handling is one of the most important safety precautions when it’s all about electrical work. Don’t hesitate to contact an electrician if you want to know more, and you don’t have all the necessary tools. Stay safe, and keep connected!
