This chart assists in understanding the relative costs of each connection technology by providing a clear comparison in total wiring times for screw and spring clamping technologies. Crimp style has been excluded due to the variability associated with contact design and the wire preparation process automation. The baseline represents the total time for connection of a ferruled wire into a screw clamp, including installation of the ferrule onto the wire. Use of stranded or solid wire with a screw clamp reduces wiring time by up to 40%. This reduction in wiring time directly corresponds to a 40% reduction in the labor cost associated with that portion of the installation. Replacing the screw clamp with a tension clamp provides a 30% decrease in wiring time by eliminating the need to properly torque the screw clamp, regardless of the type of wire used in the installation. The greatest time saving comes with the use of a push-in connection, which improves wiring efficiency by 40% with ferruled wires. Transitioning from a ferruled wire screw clamp combination to solid wire and push-in connections offers a staggering 80% savings in wiring time with only a minimal reduction in pull out force.
