What is the correct lug for use on flexible conductors?
Flexible conductors have a larger diameter compared to a nominal stranded conductor of the same nominal cross-sectional area.
Since the diameter of the flexible conductor is larger, it is difficult to insert into the barrel of a lug of the same cross-sectional area.
One method of terminating is by using the next largest lug size and crimping with a half hex and flat dye. Alternatively, a special lug suited to flexible conductors can be sought.
Further information on crimping techniques can be obtained from lug manufacturers.
