The medium, yellow connector is best for splitting home runs with two #10-gauge (6.0 mm 2) or three #12-gauge (4.0 mm 2) wires. The small, blue connector is ideal for connecting one fixture onto the home run, or a small junction of four fixtures.

You will need some direct-burial wire to make the connections. A two-step installation process ensures a fail-proof connection in every installation. Each wire connector has two components: a tin-coated copper butt splice and an adhesive-lined heat shrink tube. They also protect from water, salt and other corrosive compounds.With any low voltage lighting system, waterproof connections are crucial to maximizing the life of the system. Heat shrink butt splices protect connections from physical abuse and abrasion. By utilizing these types of splices you are creating a moisture proof barrier that will last. That or your tool is too close. Why use heat shrink butt splices? Heat shrink butt splices offer the highest level of environmental protection available. If you see bubbles or discoloration in the wire insulation or the heat shrink you are using too much heat. Once you are satisfied, use the proper heat gun or torch to correctly heat the outer heat shrink. Now, perform a tug test to make sure that the wires do not pull out. Using the proper tool, you will crimp the side of the butt splice creating a solid connection. So now, you insert the wire into the butt splice until the tip touches the indentation. Each butt splice has an indentation inside of it in the center where your wires should meet. This includes cutting and striping the wires to the correct length. They are designed for use with wires between 22 AWG - 10 AWG. How do you use heat shrink butt splices? Well, you start by prepping your wires. These heat shrink butt splices provide a durable, rugged, environmentally sealed connection. Terminals are a necessary element in any electrical systems. Other methods of connection may not offer the same level of protection. Remember, butt splices are useful for their rapid installation and durability. And now you've created a durable, environmentally protected connection. Be careful not to burn the butt splice or the wire insulation. Once your wire is properly crimped, apply heat to the butt splice working outward. Before you heat it, don't forget the tug test. Alternatively, you can crimp the other end creating a dead end. Next, you simply repeat the process on the other side. This crimp bends the connector around the wire creating a solid connection. So, the stripped wire is inserted into one side of the butt splice and crimped with the proper tool. Otherwise, you run the risk of damaging the wire due to exposure. Be careful to make sure that the butt splice and the wire insulation are touching. Inside of the butt splice, you will see an indentation your wires should butt up against. First, make sure you have correctly stripped the wires to the proper length.

Heat shrink butt splices create an environmentally sealed connection to handle harsh conditions. Their economical pricing as well as their ease of use make them common in electrical systems. Butt splices are a type of connector used to safely connect one or more wires to another wire.
