What is the proper procedure for the order of compressions when joining conductors?

The proper procedure for the order of compressions when joining conductors is to work from the center outward. This method ensures that the force is distributed evenly across the joint, which helps to maintain uniform compression and can lead to a stronger and more reliable connection. When starting from the center and moving outward, you effectively reduce the risk of creating stress points or gaps that could lead to a poor electrical connection.

Working from the ends inward or random order may not create an optimal connection, as these methods can create uneven pressure or insufficient contact in the critical areas of the joint. Starting with the largest sections might seem intuitive, but it doesn't address the need for uniform compression across the entire joint. Thus, the center-outward approach is considered best practice for maintaining the integrity and performance of electrical connections in conductors.
