Connecting two electrical cables together is a common task for electricians and DIY enthusiasts alike. It is critical to make safe, dependable connections to avoid electrical faults and potential fires. There are several ways to connect wires, including soldering, twisting, and using connectors such as crimps, lever nuts, and screw terminals. The choice of method depends on the specific application, such as whether the wires carry mains voltage or not, and the availability of tools.
Characteristics and Values Table for Connecting Two Electrical Cables
| Characteristics | Values |
|---|---|
| Safety Precautions | Always turn off the power before working with electrical cables. |
| Wire Stripping | Strip about 3/4 inch of insulation from the end of the wire. Avoid nicking or gouging the wire during this process. |
| Wire Joining Methods | Soldering, crimping, twisting, wire nuts, push-fit connectors, electrical tape, hot glue, alligator clips, ultrasonic welding, and more. |
| Wire Nut Techniques | Twist wires together first, then screw the wire nut over the ends. Alternatively, hold wires parallel and twist the wire nut over them. Ensure no bare wire is exposed. |
| Wire Types | Stranded wire, solid wire, copper, aluminium, and other non-ferrous metals. |
| Connectors | Wago/lever nuts, push-in connectors, screw terminals, spade connectors, ring connectors, bullet connectors, etc. |
| Clamps | Metal clamps can be tightened with screws to securely grip cables. |
| Cable Connectors | Used to safely and easily join cables or sets of wires during electrical work. |
| Splicing | Splicing joins wires together and can be done inside or outside a fixture box, using a junction box. |
| Tug Test | Always tug on connections to ensure they are secure. |

Using crimp connectors
Crimp connectors are commonly used in auto electrics, but they may be too large for domestic electrical appliances. They are also used with stranded wire. The first step is to determine the type of connector you are crimping. Connectors come in different shapes and sizes, and it is important to consider whether it is an insulated or non-insulated connector and what gauge wire it is for.
Once you have the right connector, strip about 1/4 inch of insulation from the wire using a stripping tool. If it is a braided wire, grip the exposed wire and twist it to make it firmer and more compact. Then, insert the wire into the connector until the insulation touches the barrel. If you are using a manual crimper, hold the jaws perpendicular to the wire and apply pressure to the handles. Place the barrel into the crimper slot and squeeze firmly.
After crimping, the barrel should be firmly squeezing the wire, with a visible divot behind the edge. The seam should be intact, and there should be a tiny bit of exposed wire. Give the wire a firm tug to ensure it is connected. Finally, seal the terminal with electrical tape or heat shrink. Some connectors come with heat-shrink insulation, but if not, you can place heat shrink tubing on the wire and use a heat gun to seal it.
It is important to note that some specifications may forbid the use of solder with crimp connectors. However, in the absence of such regulations, adding a small amount of solder may not be harmful.

Soldering wires
Soldering is the process of joining two or more electronic parts together by melting solder around the connection. Solder is a metal alloy that creates a strong electrical bond between the parts when it cools.
To begin the soldering process, you will need a soldering iron, solder, and some wire. Firstly, strip the wires to expose about one inch of material on both wires. Then, twist the strands together to create a single core. Ensure that the strands are tightly twisted to prevent weak joints and loose wires.
Next, you can begin the soldering process. Place the wires together, ensuring they are tightly twisted and form an X-shape. Line up the centres of the exposed wires and bend one of the wires down, twisting it around the other wire. Repeat this process with the other wire so that your splice looks even on both sides.
Now, you can melt the solder directly onto the wires to secure them in place. Use the flat edge of the soldering iron for better heat transfer, holding it at a shallow angle. Keep the iron stationary and in the centre of the joint. Remove the soldering iron and let the solder cool down naturally. Don't blow on the solder, as this will cause a bad joint.
Finally, cover and waterproof the exposed wires to seal them.

Alligator clips
To connect two electrical cables together using alligator clips, you will need a package of alligator clips and two wires with stripped ends. First, strip away an inch or so of the plastic covering at the end of the wire you want to attach to the alligator clip. You can do this by pinching wire strippers around the wire and pulling away the coating. Next, thread the exposed end of the wire through the circular hole at the back of the clip. Then, screw the exposed end of the wire into place. Some alligator clips may require crimping or soldering to attach to the wire.
If your alligator clip has two metal wings sticking out from the sides, place the exposed end of the wire between them and use pliers to squeeze the wings over the wire to hold it tight. If it does not have these wings, loop the wire as tightly as possible around the end of the clip and squeeze it flat with the pliers. You can then use a soldering iron and solder to establish a permanent connection.

Electrical tape
While taping wires together with duct tape or electrical tape is not recommended as a permanent solution, it can be used to temporarily secure cables out of the way while work is being carried out.
If you do decide to use electrical tape, first twist the ends of the two wires together. Then, lay the twisted part of the wires onto a strip of electrical tape and wrap the tape around the wires tightly 5-6 times, ensuring that all the wire is covered. Once you've finished wrapping, give the connection a tug to make sure it is strong.
There are several other ways to connect wires without soldering, including the alligator clip method, hot glue method, and crimping method. The crimping method is the strongest but requires the most specialised tools.
For a more permanent solution, you can use wire nuts, which are more secure than electrical tape and don't require any special tools.

Hot glue
Using hot glue to connect two electrical cables is a quick and easy method that can be used for a range of applications, from electronics manufacturing to woodworking.
Firstly, you will need to prepare the wires by stripping the insulation and twisting the ends together. Make sure that the wires are firmly twisted and that there is enough length to make a secure connection.
Now, you can get started with the hot glue gun. Heat up the gun and, once ready, hold it perpendicular to the twisted wires. Apply a generous amount of glue to the connection by squeezing the trigger. Use the nozzle or a pencil to swirl the glue around the wires, ensuring an even coating. The glue will cool quickly, so you won't need to clamp the wires down.
This method is strong and will also insulate the wires. However, it is important to note that hot glue may not be the best long-term solution for connecting electrical cables. Some people have experienced issues with hot glue and electronics, and it may not adhere well to certain materials. There are alternative methods for connecting wires, such as using electrical tape or crimping, which may be more suitable in certain situations.
