Wire nuts or connectors are often used to secure connections for switches, fixing lights, receptacles, and many other devices. If you are looking to buy these for a wiring project, you have come to the right place. Here is a simple guide on how to choose suitable aluminum wire nuts.
Size and color matters
Aluminum wire nuts come in different colors and sizes, and there is no one-size-fits-all. You can tell that a nut is wrong if it is too big or too small to accommodate the wires being connected to it. The packaging of the nuts often has a chart that tells you what color of nut you are supposed to use with which kind of wire. For example, a gray nut may accommodate two 22 gauge stranded wires.
Consider the environment
It is essential to understand where the electrical wiring is going to be placed. Sometimes, you may want to use the wires in a hot environment or in a hazardous location where there will be toxic gas or combustible liquids or vapors. In these circumstances, you will have to check if the wire nut has proper insulation, and in case of a hazardous environment, the connector should have a protective shield.
Strip the wire ends properly
Before you connect the wire to the connector, you need to strip the tail end. You can use a wire stripping tool for this purpose. While performing this step, keep the connector package handy. The label usually mentions how much of the bare wire you can expose. In most cases, it is approximately 1/2 or 5/8 inches. Exposing too much or too little of the wire can lead to a faulty connection.
Choose the ideal aluminum wire nut
Different projects demand different kinds of wire nuts. Twist-on wire connectors are typically used in wiring for ceiling fans, light switches, can lights, and so on. Conversely, winged twist-on connectors are used in large projects where establishing multiple connections is required. They make easy-to-use, fast, and secure electrical connections. Then, there are underground waterproof connectors, which are made of 100 percent sealant. These are used for outdoor pet containment systems, sprinkler systems, and low- voltage outdoor lighting. So choose the right connector based on your requirement.
Check the connector’s features
If you are using aluminum wires in an area where there is constant electromagnetic interference, you need wire nuts that can establish a connection undeterred by interference. Furthermore, the aluminum wire nuts will need to have special built-in features for the same.
