Cable Lugs

Nick Parker
The project specification says, "All compression connectors for 10mm2 and larger conductors shall have a manufacturer's reference compression die number and conductor size printed or stamped on the connector".


If the marking requirement is not complied by lug vendors on the pad/tongue of the lugs, the same can be pressed into the lugs during crimping, using appropriate dies. Is this acceptable?


 I say this because the pressed marking on the crimping part would be compared with the factory markings on the pad/tongue of the lugs for verification.

Even if the factory markings are not provided, the pressed marking on the crimping part would be verified with the catalogues /datasheet of the lugs.

    Usually the hexagonal dies used to fit/compress the lugs onto the cable end - will stamp the size of die used onto the lug. 


    The lugs usually come with a size of lug already stamped on it from the manufacturers (On the flat part of the lug)....... say a 95/12 would mean that this lug is for  a 95mm cable and has a 12mm hole - so it can/should be connected by a  12mm threaded bolt. 


    I think the requirement is for your crimping tool to stamp the lug with the size of die used to do the crimp. (So don't use a pin type crimping tool or pliers or anything else that wont stamp the size of tool used)
