How far do you insert a stripped wire into a contact before you crimp it?

When crimping a stripped wire into a contact, it is important to ensure that the wire is fully inserted to ensure a secure electrical connection. The correct practice is to insert the wire until you can't see the end of it through the inspection hole. This guarantees that the stripped portion of the wire is adequately enclosed and compressed within the crimp. A proper crimp connection enhances the conductivity and reliability of the connection, reducing the risk of electrical failure.

Inserting the wire fully into the contact also allows the crimp to grasp the wire insulation correctly, ensuring that the strain relief is effective and that the connection does not become loose over time due to movement or vibration. Proper insertion is a fundamental part of maintaining the integrity of the electrical systems in aircraft armament.
