2/0 AWG ring terminals for high-current wiring

This two-piece set provides insulated ring terminals sized for 2/0 (00) AWG cables measuring .3648 inch in diameter. The terminals are intended for car audio amplifiers, high-current power feeds and ground wires where a secure stud connection is required. Each terminal accepts a 5/16" US Custom stud (.312 inch) or M8 metric equivalent.

Brazed seam barrel and gold plating handle heat

The brazed seam construction prevents the barrel from splitting during crimping, maintaining mechanical integrity under vibration. Gold-plated contacts reduce resistance and resist oxidation, supporting continuous current up to 283A without excessive thermal buildup at the joint.

Red and black boots identify polarity on the job

Colour-coded insulating boots cover the crimp area, simplifying polarity identification during installation and service. The ring lug design allows the connector to be bolted directly to a bus bar or chassis stud, eliminating the need for additional lugs or adapters in high-vibration environments.

Questions about this item

How do I crimp the 2/0 AWG terminal so the brazed seam does not split?

Strip the wire to expose 0.3648 inch of conductor, insert fully into the barrel, then crimp with a 2/0 AWG hex die — the brazed seam prevents splitting when the correct die is used.

Will the gold plating wear off and require re-plating?

The gold plating resists corrosion for the terminal's service life; no re-plating is needed unless the connector is physically damaged or overheated.

At what current does the 283 A rating become a thermal limit?

Continuous loads near 283 A will heat the terminal; the brazed seam and gold plating delay failure, but sustained current above that rating risks insulation damage.
