How to Use a Wire Connector? (Quick Guide)

May 27, 2021 2 min read

Electrical solder wire connectors are a practical innovation, as they help you splice two current-carrying wires together. Moreover, the installation and other electrical wiring projects have become much easier with the wire connectors. 

Not to mention, even a non-specialist can connect two wires with a wire connector using a few tools. However, there are different types of wire connectors; and using them is also different. Let’s explore how to use the simplest form of wire connector. 

Turning off the power: This is the primary step of using a wire connector. Never try to use the wire connector with the power turned on. 

Choose the right size: Get the right size wire; a wrong size wire can lead to electrical failure and other damages. The electrical current flows through the wires and goes directly into the wire connector, and the current causes the wire to expand—hence, getting the right size wire is essential. 

Moreover, once the electricity is off and the mechanism returns to the average temperature, the wires will contract and become normal. If your wire is not of the right size, it will either pop off or fall off when the wire contracts or expands. 

Tip: Read on the sides of the connector box to understand the size of the wire. 

Stripping the wire: The right way to strip the wire is to use a proper wire stripper. Remove the coating from the ends of the two wires. However, make sure that you strip only ⅜ inches of the coating and not more than that. 

Place the ends together: Place the wire together in a parallel direction. Not to mention, a lot of electricians also twist the two wires together before placing the connector. Twisting the wires together is indeed a good technique as it makes the connection stronger, and it is difficult for the connection to be separated.

Placing the connector: Once you are done with twisting the wires or lining them up in a parallel direction, place the wire connector on the top of the conductors of the wires. However, ensure that no material is popping up from the exposed conductor. 

Final twisting: Once the connector fully covers the exposed wires, twist the connector in a clockwise direction. Make sure that the connection is tight and there is no air. Test the strength by holding the connector and try to pull the wire. If the cap falls off the connector, you need to redo the whole process. If not, turn on the electricity and test your connection.
