What tool is used to set the teeth on an automatic splice?

• A. Hydraulic press with dies
• B. Turning internal whistle 30 degrees
• C. Tooth alignment and setting tool
• D. Jerking the conductor

Answer: (C)

The key idea here is that the teeth on an automatic splice are the gripping features that bite into the conductor strands to hold the splice securely. To work properly, those teeth must be positioned and seated with exact alignment and depth so every tooth engages evenly and the strands aren’t nicked. A tooth alignment and setting tool is designed for this precise task: it positions each tooth, checks spacing, and seats them correctly so the bite is uniform and reliable. If you try to use a general press or an improvised method, you risk uneven bite, damaged strands, or a weak mechanical and electrical connection. The dedicated alignment and setting tool ensures consistent, correct tooth engagement, which is why it’s the right choice.
