How do you properly use wire connectors terminals?

Here are the basic steps you should put in mind when using wire termination:

  1. It is important that before you start making electricity related projects, that wires are not connected to a live power source. Make sure that the power circuit is turned off to avoid hazardous accidents.
  2. Insert the stripped wire into the end of the terminal and press it firmly until the wire insulation meets the terminal insulation. Never allow the bare wire to be exposed to avoid problems in the future.
  3. Place the end of the terminal into the crimp tool. Make sure that the terminal is placed at the correct rise size and that the casing is placed in the middle of the rise.
  4. Gently close the tool to grip the casing. Afterward, squeeze the tool as hard as you can. Check if the crimp is successful by pulling the wire from the terminal lightly. If the wire does not come off, then the crimp is successful.
