How to Make a Wire Nut Splice Waterproofby Dakota Wright
Electrical fencing systems are designed to stop when they come in contact with water, to prevent electrical shock to the owner or their pets. Wire splices in the fencing system are susceptible to water infiltration during a rainstorm or heavy dew, which can permanently damage the fencing. To prevent water damage to the converter you'll need to install a waterproof wire nut cover at every wire splice. Waterproof wire nut covers come in many sizes; consult the packaging to find the right size for your fencing wire.
Turn off the electrical current that powers the fencing converter. To do this, turn off the breaker in your electrical panel that supplies the perimeter fencing with power.
Remove the old wire nut and examine each wire for damage. If damage exists, cut off the the old wires below the twist. Grasp the wire with wire strippers three-eighths of an inch from the end; squeeze the wire strippers firmly to cut through the insulation jacket. Pull the insulation jacket off the end of the wire.
Tie both wires in a knot four inches from the end so that the wires don't inadvertently pull apart and lose connection. Insert each wire into the wire nut. Hold the wires firmly between your thumb and index finger. Twist the wire nut counterclockwise with the other hand.
Open the waterproof wire nut case by pushing the cap up. Push the wire nut into the waterproofing gel as far as you can. Close the lid on the waterproof wire nut case until you hear the audible click.
Wrap electrical tape around the wires, starting one inch below the wire nut case. Continue wrapping electrical tape until you reach the top of the waterproofing case.
