What is the ER of a short splice?

The idea being tested is how much current-carrying ability a splice preserves compared to an unspliced conductor. ER here means the efficiency of the splice in carrying current relative to the original conductor, essentially the percent of ampacity kept after the splice is made. A short splice is designed to add as little extra resistance and heating as possible. Because it keeps the splice length small and makes clean, tight connections, the added resistance is minimized. In practice, a properly made short splice retains about 90 percent of the conductor’s original ampacity, giving an ER of roughly 90%. The other percentages would indicate larger losses than what a well-made short splice typically produces, which isn’t consistent with standard practice for this splice type.
