Short answer: copper cable lug models should be indexed by cable size, barrel type, palm hole, palm width, plating and crimping die requirement.
| Tubular copper lug | Used for power cable termination and busbar connection. Confirm cable size and palm hole. |
|---|---|
| Long barrel lug | Used when extra crimping length or mechanical strength is required. |
| Two-hole lug | Used where the equipment terminal has two bolts or anti-rotation requirement. |
| Tin plated lug | Used to improve corrosion resistance and contact stability. |
A copper lug with the correct cable size can still be unusable if the palm hole or equipment bolt size is wrong.
