This is important as if the wire pulls free at any point, you will lose connectivity and possibly create a hazardous situation. If you feel any give, then you have not properly crimped the connector. Apply gently pressure pulling the two pieces apart. To perform this test, simply hold onto the wire in one hand and the butt splice in the other. Now you should perform a gentle tug test to ensure that the wire does not pull free. Now that your wires are properly stripped to the correct length and one side has been inserted, you will want to crimp that side of the butt splice with the proper tool. The insulation should butt up to the outside of the barrel body. Next, you will want to strip your wires so that the bare conductors touch the indentation you will see inside of the butt splice barrel. The first step is to select the correct size wire connectors and style for the task at hand. Stress Relief How do you use a butt splice?īutt splices are used by crimping them to create a long-lasting durable bond. One question we often get from our customers is how to use them. As you can see, the advantages of these connectors are numerous which explains why they are such a common type of connector. If we are talking about an epoxy lined heat shrink butt splice, then you can add protection from moisture, chemicals, and stress to that list. These electrical connector types are built for longevity They are inherently durable which means that they can protect the connection point from impact and abrasion. How is a butt splice advantageous?īutt splices are advantageous as they allow you to connect two or more wires in a way that offers various protections to the connection point. Now let us take a look at what makes these types of connectors advantageous. How do you know if your existing butt splices need to be replaced? Are your butt splices faded? Are your butt splices cracked? If so, then it may be time to replace those splices with new ones. Even though they are ideal for new wire and cable installations, butt splices are equally useful for replacing older parts or performing maintenance. In order to select the correct type of connector for your task, it is important to know what advantages that they offer.īutt splices are implemented in connecting multiple wires together in order to complete an electrical circuit. Pacer's large inventory of butt splices are offered in heat shrink, nylon, vinyl, and non-insulated. These types are useful in situations where the environment is not as much of a direct concern. The alternative to epoxy lined is either vinyl, nylon, or non-insulated. Epoxy lined is only available with heat shrink butt splices. To properly activate the epoxy, heat the ends of the butt splice with the proper tool after crimping. This is useful in marine conditions or other environments where hazards may be present. This glue, or epoxy, reacts to heat and expands creating an environmentally sealed connection. Why is this important? Many manufacturers do not line the interior of their butt splices with a melt-able glue. When selecting which type of butt splice to get, pay special attention as to whether they are epoxy lined or not. "Their ease of use and economical pricing makes them very common in electrical systems." Their ease of use and economical pricing makes them very common in electrical systems. We will discuss the various types of butt splices further down the page. Crimp connectors and other electrical connectors ensure quality connections. They could also be used to connect two or more smaller gauge wires to a single wire. For example, step-down butt splices are meant to connect a higher gauge wire to a lower gauge wire. Butt splices are one of many types of crimp connectors used to safely connect one or more wires to another wire. It depends on which style of butt splice you are using and the task at hand.
