UNDERGROUND FEEDER CABLE SPLICE KIT, 14-8 AWG COMPLETE KIT: This 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 Polycarbonate 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 a ground or two solid conductors with a ground. They range in size from 14-8 AWG. Repair of underground feeder UF-B cables rated for 600 volts, ranging from size (Min.) #14/3 without ground wire up to (Max.) #8/3 with ground wire. In cases of dig-in repair or extensions, the MAVooPoo UF Splice Kit, Standard versions, will produce a connection that is insulated and moisture resistant. UPGRADED 4-SCREW LOCK & INSPECTION HOLE Upgraded 4-screw fastening design with a central inspection hole. It allows soldering reinforcement for enhanced reliability, delivering superior pull-out resistance, stability, mechanical strength and vibration resistance. Comes with set screws of two different drive types—Slotted Drive and Allen Drive Set Screws—to accommodate varied assembly tools and operational scenarios. This compatibility enables flexible, reliable installation procedures that satisfy the diverse demands of on-site wiring projects. Application Temperature 0°F to 120°F(-18°C to 49°C). Operation Temperature -67°F to 230°F(-55°C to 110°C). TO COMPLETE A SPLICE OF #14 TO #8 GAUGE UF COPPER WIRE, FOLLOW STEPS 1 THROUGH 9: WARNING!: Turn power off before installing or removing terminal or connector. All work should be done according to appropriate electrical codes. 1. Remove 2” of jacket from UF cable. 2. Strip insulation from each wire to approximately half the length of the butt connector. 3. Clean cable surface and wipe dry, approximately 4 inches per side of the splice. Lightly abrade the two clean insulation surfaces. Clean cable surface and wipe dry again. 4. Slide the enclosed long piece of heat shrink tube over one end of the wire. 5. Insert wires, one at a time, into the brass connector making sure that the wires of desired connection are in the same brass sleeve. Make sure that the wires are inserted an equal length into the brass sleeve so that the set screw can engage into the copper of each wire. 6. Tighten screws with 8 inch pounds of torque. The Inspection Window on the butt connector allows visual inspection of wire insertion depth, ensuring all wires are fully seated. Additionally, the cutout serves as a dedicated soldering access point for tinning and wire bonding. For stronger, more secure and stable connections, supplementary soldering through the central access hole is highly recommended. 7. Slide long piece of heat shrink over connection centering it with respect to the brass/plastic connector assembly. 8. Apply heat to the shrink tube with a torch or heat gun starting in the middle of the shrink tube, moving out to each end. Properly installed, shrink tube will be smooth and conform to the cable. Adhesive should be visible at each end of the shrink tubing. 9. Apply heat to tube until adhesive flows out on both ends of tube. Tips: - Avoid overheating. Please use a temperature-adjustable heat gun or small propane torch. The use of lighters is not advised. - To prevent air bubbles be sure to heatfrom the center out. Heavy-wall heat shrink tubing starts shrinking at 257 °F (125 °C), with an optimal shrink temperature range of 257 °F to 392 °F (125 °C to 200 °C). Keep your heat source moving. If tubing seems tobe scorching or getting too hot, increase the distance from the heat source. To prevent the splice from slipping, hold the splice level untilit begins to cool. - Us
