3M™ Motor Lead Connections-Inline


3M 5314

Each kit makes three splices. Lugs not included in kits. Feeder of 250-500 kcmil (150-240 sq mm), motor lead 4/0 AWG-500 kcmil (120-240 sq mm). These kits are designed to be used with copper compression, one- or two-hole lugs. After being crimped onto the cables, the lugs are bolted together in an inline configuration, then insulated and sealed with the 3M Motor Lead Splicing Kit. Each kit contains all the necessary materials (except lugs) needed to make three splices. The lugs must be purchased separately. 3M™ Scotchlok™ 30000 Series copper compression lugs, or other UL listed copper lugs, can be used.

3M™ motor lead pigtail connections and inline splices are designed to splice 1000 V or less, non-shielded feeder and motor lead cable. The splices are made with a slip-on lug cover made of EPDM rubber. Each kit makes three splices and is designed exclusively for the abrasion, moisture, grime and temperature extremes of the industrial environment. 3M™ motor lead connections meet requirements for CSA certification and NRTL certification.
