3M™ Motor Lead Splicing Kits 5300 Series are a series of kits used for splicing motor lead cables to incoming feeder cables. The splice’s main component, the lug or splice cover, is made from EPDM rubber either as a slip-on or as a cold shrink insulator. A mastic is used for the moisture seal on the pigtail kits. The 5/8 kV kits, used for shielded feeder cables, utilize a high dielectric constant stress control material or the feeder cable’s electrical stress control. These kits are 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 or pigtail configuration, then insulated and sealed with the 3M motor lead splicing kits. Each kit contains all the necessary materials (except lugs) needed to make three splices. The lugs must be purchased separately. 3M Scotchlok™ Copper Lugs 30,000 Series, or other UL listed copper lugs, can be used.
