Which tool should be used to crimp solderless crimp connectors?

• A. Any pliers
• B. A tool recommended by the manufacturer
• C. A hammer
• D. Diagonal cutters

Answer: (B)

Using the tool recommended by the manufacturer is essential because solderless crimp connectors are designed to be deformed in a very specific way to grip the conductor and seal properly. The manufacturer’s tool and dies matches the connector type and wire gauge, ensuring the crimp height and alignment are correct every time. This yields a reliable, code-compliant electrical connection. General tools like pliers or diagonal cutters can apply uneven pressure, over- or under-crimp, damage insulation or conductor strands, and create a loose or unreliable connection. A hammer cannot produce the precise, repeatable crimp required, and would likely ruin both the connector and the wire.
