What is the maximum allowable protrusion of conductor strands in a crimp barrel?

The maximum allowable protrusion of conductor strands in a crimp barrel is guided by safety and performance considerations. A protrusion of 1/32" (1 mm) is commonly regarded as the standard limit to ensure that the conductor strands are securely held within the crimp barrel, which is crucial for maintaining good electrical contact and preventing issues such as sparking or overheating during operation.

Having too much protrusion can lead to inadequate crimping, which compromises the integrity of the connection. It may also expose the conductor strands to the environment, increasing the risk of corrosion or short circuits. Thus, the choice indicating a maximum allowable protrusion of 1/32" aligns well with industry standards that prioritize reliable and safe electrical connections.
