About this detail

A long barrel compression connector features a two-hole tongue and clear heat shrink tubing applied over the crimp portion. An accompanying schedule lists catalog numbers, hole sizes, and bolt spacings for wire sizes ranging from number 6 American wire gauge up to 750 thousand circular mils for manufacturers including Thomas & Betts, Blackburn, and Burndy. Installation notes specify the use of twelve to fifteen ton rated crimping tools with manufacturer-matching dies, require dual rated aluminum-copper lugs when feasible, and mandate clear heat shrink tubing over all power terminations for number 6 American wire gauge and larger.
