How to use ferrule crimpers

See below for our guide on how to use ferrule crimpers and crimp boot lace ferrules. Firstly a bit of information about ferrules:

What are wire ferrules?

Wire ferrules or cable ferrules are a small cylindrical sleeves usually made from tin plated copper or steel. They are designed to be slid over the end of a stranded cable after any insulation has been removed and crimped into place. The most commonly used type of ferrule is the bootlace ferrule which is what we are looking at here. They are also known as cord end terminals.

Why do we use wire ferrules?

The purpose of the ferrule is to hold the strands of the cable together for easier and tighter termination (connection), reducing the possibility for any heat build up in the connection due to a bad connection and high resistance.

Wire ferrules also aid with any future work on the on the circuit such as when repeatedly installing/removing stranded cables during fault finding. Without ferrules the end of the cable can become weak and damaged. Ferrules also give a much neater finish.

Many wire ferrules have a small plastic cone shaped sleeve on the end to help guide the cables through the ferrule and cover any exposed uninsulated cable. In some cased this sleeve also aids with guiding the wire into the terminal in which it is to be terminated.

The photos below show individual cables which have been crimped with boot lace ferrules. Connected into din rail connections in an intrinsically safe junction box leaving a very neat and tidy finish.
