Instructions
Pick the conductor size . Flex / DLO classes are separate entries — DLO cable is larger per kcmil and often takes the next barrel up.
Read the die color code and the W or U die set for your crimp tool.
Choose the connector by bolt size in the table. Two-hole "N" pads are the NEMA 1-3/4″ spacing pattern.
#2 solid conductor uses the #3 stranded barrel (the "#3 AWG / #2 SOLID" entry).
Crimp Tooling
PAT600-18V — 6-ton, crimps up to 600 kcmil CU, uses "W" dies .PAT750XT-18V — 12-ton, crimps up to 750 kcmil, uses "U" dies .

Burndy is today a Hubbell brand; some catalog numbers may have been superseded or consolidated since
printing. A dash (—) means the card lists no product for that position.
Two-hole connectors marked with the "N" suffix use the NEMA standard 1-3/4″ hole
spacing. Die color codes correspond to the index number embossed on the die; always match the color or
index stamped on the connector barrel to the die before crimping.
