WIRE SIZE EQUIVALENCY CHART

When sizing compression lugs for flex, DLO and welding cables, the diameter varies from that of standard
building wire. The chart below will help you to find the equivalent wire size for proper lug fitment. Always check
manufacturer specifications for proper termination directions and follow all safety guidelines.
