When installing an automatic splice, how are the teeth set into the conductor?

• A. Teeth are set with a hydraulic press and the appropriate dies
• B. Turning the internal whistle 30 degrees to the lock position sets the teeth
• C. Teeth are set with a tooth alignment and setting tool
• D. Jerking the conductor several times sets the teeth

Answer: (D)

In an automatic splice, the teeth are designed to bite into the conductor when the joint is subjected to movement. After the conductor is placed in the splice, you apply a few sharp jerks to seat the teeth into the strands. That dynamic action drives the teeth into the conductor and locks the splice in place, giving a secure grip without needing additional crimp dies or tools.

Hydraulic presses or a tool to align or set the teeth aren’t part of the standard method, and there isn’t a rotating mechanism to “set” the teeth. The teeth are meant to engage the conductor through the deliberate motion of jerking, which ensures a proper bite and a dependable connection.
