What is a splice kit?

A 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. Inside the heat shrinkable tubing is an adhesive liner that will melt when heated. This will coat the connection and cover the wire with adhesive, oozing out the ends of the tubing as it shrinks. This method can be used if wiring is deep in the ground and no possible damage from gardening tools hitting it.

How to splice a wire?

Before 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. Then, insert each conductor into the connector and match the colors. Tighten the screws in the connector, and heat the shrink tube with a heat gun to complete the seal.

Why do you need waterproof junction boxes?

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. This will protect the connections from corroding due to moisture and chemical elements from the surrounding ground.

Can you use liquid tape to seal wires?

I've decided to use some liquid tape (with a new bottle), which seems like the best way to seal the wire perfectly from the outside and it's neighbor wire, and then some professional electrical tape on top of that (strong adhesive, high temp) once it cures. I like this tape over silicone self-sealing in this case because its more durable, particularly if stepped on (even though that's unlikely in this small space.)

if the damaged wire is in a wall you will need to either replace the entire section of cable between the electrical boxes, or install a new electrical box to repair the break. If you are not familiar with doing this please contract a licensed electrician to perform the work.

How to insulate a wire?

You have two choices at this point to insulate the conductors. 1)electrical tape, and 2)heat shrink tubing. If you use the latter, you will need to slide those on each wire at this point before connecting the matching conductors to each other, and then slide a larger diameter tube over all the conductors. Now connect the matching conductors wires by twisting them together so they are still parallel the cord. Wrap each connection with electrical tap separately or slide the heat shrink tubing over the connections and apply the heat from a heat gun or even a hair dryer to shrink the tubing on each conductor. Finally, wrap both conductors together with electrical tape or slide down the shrink tube and heat it as before to insulate the splice.
