Match the terminal, not just the wire gauge
Check the terminal part number, barrel construction, conductor size, insulation support and required crimp geometry. Solid contacts, stamped contacts, ferrules and cable lugs use different tooling. Gauge alone does not establish compatibility.






Preparation and inspection
Identify the terminal and wire; strip to the specified length; position in the matching tooling; complete the operating cycle; inspect and test the first sample before continuing.
