What is the most essential function of a wire nut?
Answer Strengthen the connection between conductors
Thanks to its insulative plastic shell and cone shape, which you twist onto the exposed wires, you can create a secure connection between two conductors. With a properly-applied wire nut, you can ensure conductors never disconnect from one another.
