💡 What is a handy way to pick the right butt connector for a repair?

Choosing the right size and metal type helps ensure a secure, long-lasting splice.

- Wire size compatibility (0.5-6 mm²) ensures a secure crimp and good conductivity
- Tin-plated copper improves corrosion resistance and current capacity
- Seamless barrel design prevents wire slip during crimping
- Use bn0.75-bn8 to match common wire gauges (roughly 22-16 AWG)
