The UF Splice Kit consists of a connector-insulation assembly and a heat shrink tube. The connector assembly contains four cylindrical set screw connectors separated by a piece of vinyl insulation. The heat shrink tube is a heavy-wall, adhesive-lined tube. Underground Feeder (UF)-B cables are flat, and typically have three solid conductors without ground or two solid conductors with a ground. They range in size from 8 AWG to 14 AWG. The most common UF cable size is 10-14 AWG. The 3M UF Splice Kit is offered in two versions: UF1 Standard Kit includes a 1.8" length terminal connector and an 8" length of heavy-wall, adhesive-lined heat shrink tube. UF2 Stretcher Kit has an 11.7 inch terminal connector and a 20 inch length of heavy-wall, adhesive-lined heat shrink tube. The Standard Kit is used in most of the applications. The Stretcher Kit is used in situations where a 7-10 inch section of the cable has been damaged or destroyed. It eliminates two connectors and a short piece of cable during repair.
