Best practice for Beanie or B Crimp connectors?

• A. Strip and twist wires before crimping
• B. Always twist without stripping
• C. Use only gel-filled wires
• D. Do not strip or twist before crimping

Answer: (A)

Exposing the conductor and keeping the strands together before you crimp ensures a solid electrical and mechanical connection. Stripping removes the insulation so the metal can be crimped around the bare copper, and twisting the stripped strands helps prevent them from splaying or creating gaps, giving the crimp barrel a uniform, secure bite. When the crimp is made over a properly prepared conductor, it compresses all the strands into a single, low-resistance contact that won’t loosen with vibration.

If you don’t strip, there’s no conductor for the crimp to grip. If you skip twisting, loose strands can fan out and cause a weak connection or intermittent contact. Gel-filled wires aren’t a requirement here, and crimping over insulation or without any stripping and twisting would similarly fail to produce a reliable connection.
