What is the ER of an eye splice?

ER is the percentage of the conductor’s original current-carrying capacity that remains after making the splice. An eye splice is designed to preserve most of the wire’s cross-sectional area, so only a small amount of capacity is lost. The standard value for this efficiency is about 95%, meaning the splice retains roughly 95% of the original ampacity. The remaining 5% accounts for slight losses due to the way the strands are arranged and in contact within the splice. Lower values would imply a greater drop in capacity, which isn’t typical for an eye splice.
