Wire connectors are available in many different sizes. They are specifically made to join a certain minimum and maximum number of wires and before purchasing, you must always check the approved list on the packaging to ensure the connector is the right one for the desired wire combination. It is advisable to keep a range of small to large connectors and their respective packaging handy to eliminate the chances of using a wrong connector size.
It is important to line up the ends of all wires before twisting on the conductor. If not done correctly, all wires will not be clamped evenly in the connector, increasing the chance of one or more wires slipping out.
A faster and cleaner way to remove the plastic coating of a wire is to use a wire-stripper. There are several brands of wire-strippers available in the market, so make sure you buy the one that best suits your requirement.
When wires get bent or twisted, they get weaker and don’t nest together easily in the wire connector. Before reconnecting wires to a switch or outlet, or rejoin several wires to a connector, it is advisable to cut off the bent wire ends and use a wire-stripper to strip the wire’s insulation to expose a clean, straight wire. This step may take a few extra seconds but it ensures your wire connection is better and safe.
At most hardware and electrical centers, there are several wire brands available and choosing the right one can get difficult. Also, the prices are different and it can be tempting to buy a cheaper brand. But remember, you get what you pay for. Premium wire brands are stronger, make better contact with connectors and work smoothly. Cheap wire brands can literally wear out in a short time and malfunction leading to calamities such as short circuits and even electrical fires.
