Heat the tube with a heat gun until it forms a tight seal around the connector. Slide the heat-shrink tube over the splice connector.Insert each conductor into a splice connector and match the conductor from the other end of the cable black to black, white to white, and ground to ground.Strip the conductors on each end of the wire. Slide the heat shrink tube onto on side of the cable. Strip the outer cable sheathing back about 3 inches. If the cable is damaged over a large area, cut out the damaged area and cut a new piece of UF cable that is the same gauge as the original wire. Browse our selection of Splice Kits from F4P. Cut the cable completely through if the wire has multiple conductors.Test the wire or cable with a non-contact voltage tester to verify that there is no power on the circuit.Use caution when digging so as not to damage the cable any further. For simplified splicing of UF cable designed with heavy wall heat shrink with sealant. Depending on the installation, the wire can be from 6 inches to 24 inches below the surface. NSI UF cable splice kit will accommodate 14/3 through 8/3 with ground UF cable and create a direct burial splice. With a small shovel, dig around the damaged electrical wire about 12 to 18 inches on either side of the break.If you cannot locate the break in the wire you should hire an electrician with an underground open/short locator to mark the location of the damage.Īn Open/Short locator is not a device available to the do it yourselfer If you recently hit the wire, it will probably be in a tripped position. Locate the circuit breaker feeding the underground wire and shut it off at the panelboard. UF cable, if you need to replace a section of wiring Splice kits can be purchased at home centers, online, and at electrical distributors for between $10 and $25 dollars, depending on the size and type of cable being repaired.
The 4-conductor splice has a plastic sleeve to isolate the connectors. Underground splice kits can come with a single conductor connector (top) to repair individual wires, or with a 4 conductor splice connector (bottom) to repair all of the wires in a cable. Underground splice kits contain a brass connector with a heat-shrink sleeve that will complete the connection and keep moisture out. Instead of digging up the wire and replacing it, you can easily repair the wire in place with an underground splice kit. As more and more homeowners add exterior lighting, receptacles, dog fences, and irrigation systems, there is a greater chance for damaging the direct burial, also called underground feeder (UF) cable, underground electrical wires.
