Step-Down Tinned Butt Splice

Step down tinned butt splices are used to connect different gauge wires together or multiple wires of the same size. So, you could use step down tinned butt splices to connect a 10 gauge wire to a 14 AWG wire, or connect a 14 AWG wire to two 14 gauge wires. The first step is to make sure you have correctly stripped the wires to the proper length. If you look inside the butt splice you will see an indentation. Make sure your wires butt up against that. Insert the wire making sure the insulation touches the butt splice, otherwise you run the risk of a weaker connection. Now, the splice is crimped with the proper tool. This crimp bends the connector around the wire which creates a solid connection. We'll repeat the process on the other side with a larger wire. After crimping, perform the tug test to make sure the wires don't pull out. Now you've created a durable connection. Remember, Butt splices are useful for their rapid installation and durability. Other methods of connection may not offer the same level of protection.
