Connector Specifications

This Zoro Select one-hole lug compression connector is built for stranded copper wire sized at 1 AWG. The aluminum body carries a gold colour code and die code 45 for quick identification during installation. It is UL Listed, RoHS compliant, and rated for up to 600 V AC at a maximum operating temperature of 300 degrees F. The seamless barrel design ensures a consistent crimp connection.

Installation Requirements

The connector suits electricians and technicians terminating a single 1 AWG copper conductor to a 1/2 inch stud. The straight tongue measures 0.88 inches wide and provides a direct mounting path. Buyers needing an inspection window to verify wire insertion should select a different lug style. Those working with aluminum conductors or wire gauges other than 1 AWG must choose a connector matched to those specifications.

Critical Compatibility

This lug is engineered specifically for 1 AWG stranded copper wire and a 1/2 inch stud size. Using a different wire gauge or stud diameter will prevent a proper crimp and compromise the electrical joint. The gold colour code and die code 45 correspond to this exact wire and connector combination. Verify both parameters before purchase to ensure a safe, code-compliant termination.

Questions about this item

Will the aluminum lug need re-crimping or replacement after repeated thermal cycles?

The seamless barrel and crimp termination are designed for a permanent connection; no routine re-crimping is required unless the conductor is damaged.

What electrical limit is reached first when the connector runs continuously at high load?

The 600 V AC rating or the 300 °F temperature ceiling will be the limiting factors under sustained current.

Does the lug generate noticeable heat or require extra cooling during all-day operation?

No active cooling is needed; the aluminum body dissipates heat passively within its 300 °F maximum operating temperature.
