Connector Specifications

This ZORO SELECT one-hole lug compression connector is built for stranded copper wire sized at 4/0 AWG. It accepts a 1/2 in stud and carries a purple colour code with die code 54. The barrel is long and the tongue sits straight at a width of 1.03 in. Rated for 600 V AC and a maximum operating temperature of 300 Degrees F, it meets CSA Certified and UL Listed standards.

Installation Requirements

Verify that your conductor is stranded copper and falls exactly at 4/0 AWG, as the connector accommodates no other size range. Ensure the stud measures 1/2 in and that your crimp tool matches die code 54 for a proper termination. The seamless barrel design requires a compatible crimping method, and the absence of an inspection hole means visual confirmation of wire insertion is not possible after assembly.

Upgrade Context

This connector replaces older lugs that lack CSA and UL listings or that use a seamed barrel construction. The jump is worth it when a project demands a seamless copper barrel rated for 600 V AC and 300 Degrees F in a straight-tongue, single-hole format. It is not suited for applications needing an inspection window, a different stud size, or a wire gauge outside 4/0 AWG.

Questions about this item

What comes with the ZORO SELECT 24C331 lug and what must be purchased separately?

The connector itself is supplied; you must buy 4/0 AWG stranded copper cable and a compatible crimp tool with die code 54 to complete the termination.

How do I choose the correct version of this connector for my cable?

This model is fixed for 4/0 AWG stranded copper with a 1/2 in stud hole and purple colour code 54; select it only when those exact parameters match your installation.

What does the 600 V AC rating mean when the lug is installed in a panel?

It certifies the connection for continuous operation up to 600 volts AC and 300 °F, provided the crimp is made with the correct die and the copper conductor is properly prepared.
