What is the correct lug for use on compacted conductors?
Compacted conductors have a smaller diameter compared to standard stranded conductors, but their nominal cross sectional area is equivalent and a lug designated for the same cross sectional area must be used on the compacted conductor.
Even though the lug will appear to fit more loosely, when crimped in accordance with the lug manufacturer’s recommendations, the end result is the equivalent to the crimping of a standard conductor.
Compacting the conductor by the cable manufacturer is just the action of pushing all the wires together, getting rid of the air gaps, ahead of time.
Note : The general practice is for lug manufacturers to manufacture a range of lug sizes that suits both the compacted and standard conductors. However, if there are any concerns, please consult your lug manufacturer.
