How To Splice Wires

Remove the Cable’s Outer Covering

  • Cut open one side of the outer covering at the end of the cable and fold it back from the wires.
    • Cut away from your body starting about one inch from the end. Cut lengthwise between the conductors.
  • Peel back the outer covering about six inches.
    • Hold the sheath in one hand and the wires in the other, then pull the sheath down.
  • Cut the sheath and any paper away from the wires with lineman’s pliers.
  • Examine the entire length of the exposed wires for cuts and nicks in the insulation.
    • If you see exposed copper, cut that part off and start again.
    • Often there’s not much wire in the junction box, so be careful when cutting and stripping.
  • Repeat this process for each cable you’re splicing.
