Tighten the screws in the connector, and heat the shrink tube with a heat gun to complete the seal. Then, insert each conductor into the connector and match the colors. This method can be used if wiring is deep in the ground and no possible damage from gardening tools hitting it.Ī better choice for wires that you fear might get cut again will be connectors with a thick protective covering on them and a silicone-based sealer inside for waterproofing.īefore you use the splice kit, you will need to cut the damaged wiring on either side of the break and strip the outer sheathing back about three inches. This will coat the connection and cover the wire with adhesive, oozing out the ends of the tubing as it shrinks. Inside the heat shrinkable tubing is an adhesive liner that will melt when heated. Step 5 - Use a Splice KitĪ splice kit containing an inline connector will join the two ends of a break securely in a polyolefin sleeve, which will shrink when heat is applied, to maintain a water-resistant connection. They have silicone inside the connector which will seal out the moisture after you have inserted the wiring.ĭo not reuse these once you remove them, however, because you may strip away too much of the silicone when you pull it off, and it will no longer be watertight if reused. These are a must when joining wires together in the watertight box. Special sealing box cable connectors provide the waterproof seal for the electrical wiring that enters the box as well. This will protect the connections from corroding due to moisture and chemical elements from the surrounding ground. If you are going to add additional circuitry to your existing wire underground, purchase waterproof junction boxes where connections can be made inside the box. Step 4 - Purchase Junction Boxes and Cable Connectors Then, dig along the sight path between the electric cables exit and entry points. Use a non-contact voltage tester afterward to confirm that the cable is no longer live. Step 3 - Dig up the Affected Wireįirst and most importantly, make sure you turn the main electrical supply off before digging or attempting any repair to, or in addition to, the electrical wire underground. may incur a small fee the best practice is to call and ask. Locating other underground wires for light poles, barns, pools, garage, etc. Most provide this service for free when locating the main power wires running from their incoming source to your meter or box. Some cover plates have a matte surface that allows them to be painted.Step 2 - Call the Phone and Utility CompaniesĪnother alternative is to phone your local electric company and use their locating service. This technique grounds the electrical box and improves the safety of the circuit.Īfter completing the connections and finishing the wall or ceiling surface around the box, attach the cover plate securely.

The free end of the pigtail is then connected to a threaded screw opening on the metal box, using a green grounding screw. For metal electrical boxes, run a third grounding pigtail (bare copper or green insulated) to the two bare copper circuit grounding wires, using a wire connector. The bare copper circuit grounding wires should also be joined together in the box, using an approved connector. With these connectors, you simply push the bare end of the wire into a grip-fit socket on the connector. Some electricians like to wrap a loop or two of electrician's tape around the base of the wire nut and wires to help reinforce the wire connection.Īnother type of approved wire connector is the push-fit connector. There should be no bare wire exposed at the bottom of the wire nut. However you do it, the wires should be connected securely enough that they don't come free from the wire nut when you tug on them. However, some wire nut manufacturers instruct to simply hold the two parallel wires together, then twist the wire nut over the bare ends of the wires in a clockwise direction. They are designed and approved for use in rework within existing structures. With standard wire nuts, some electricians prefer to twist the wires together first with pliers, then screw the wire nuts over the ends of the wires. Product Details Tyco Electronic's Non-metallic splice and tap kits provide a fast and reliable method for splicing or tapping 2 wire w/ ground and splicing 3 wire w/ground non-metallic cables up to 300 volts. Using approved wire connectors, join together the conducting wires with similar insulation colors. The Spruce Home Improvement Review Board.
