Most Richards copper lugs are seamless copper tubing, tin plated, marked with conductor size and die information, and UL listed. Tables below follow the Richards connector catalog. Dimensions are in inches. For the two-hole NEMA copper lugs (CL-2N), see our CL-2N guide. For other sizes, contact Powertech Associates.
Wire sizes #8 to 1000 kcmil. The bolt size is the part number suffix.
