Difficulty: EasyWire Preparation Tools

An apprentice electrician is preparing the end of a stranded insulated wire for a screw terminal connection. What is the correct chronological sequence of steps to properly prepare the wire using standard hand tools?

  1. 1Cut the insulated wire to the required length using diagonal cutters.
  2. 2Select and seat the wire into the matching AWG gauge notch on a wire stripper.
  3. 3Squeeze the handles and slide the stripper forward to pull off the insulation slug.
  4. 4Gently twist the exposed copper strands together.

Answer

The proper sequence begins with cutting the wire to length, selecting the matching AWG stripper notch, stripping the insulation slug from the conductor, and finally twisting the exposed strands together.
Proper wire preparation follows a logical mechanical progression: first cut the wire to length, then select the matching AWG notch to safeguard the conductor, strip the insulating jacket, and finally twist the exposed strands to prevent splaying.

Step-by-Step Solution

1
Cut the insulated wire to the required length using diagonal cutters.
A correctly sized piece of insulated wire.
Wire stock must be cut to length before the ends can be prepared.
2
Select the correct AWG notch on the multi-gauge wire stripper.
Proper alignment of the cutting blades with the insulation diameter.
Choosing the matching notch prevents nicking or severing underlying copper strands.
3
Squeeze the handles and pull the insulation jacket off the conductor end.
Exposed bare copper conductor of the required strip length.
Exposes the conductor needed for making an electrical termination.
4
Twist the loose copper strands together clockwise.
A compact, cohesive stranded conductor end.
Keeps loose strands together to prevent stray wire shorts during terminal installation.
