When using butt splices, the first step is to make sure you have properly stripped the wires to the correct length. If you look inside the butt splice you will see an indentation your conductors should butt up against. 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. Next, repeat the process on the other side and perform the tug test to make sure the wires dont pull out. And now you've created a durable connection. Butt splices are used for their rapid installation and durability. Other methods of connection may not offer the same level of protection.
