One-Hole Compression Lug 300 kcmil

The Burndy YAD31M12E12 is a copper ring terminal designed for crimped connections on large-gauge conductors. It accepts wire from 300 kcmil to 350 kcmil and features a long barrel for extended crimp area. The tin-plated finish resists corrosion in industrial environments.

1/2 in Stud Long Barrel Design

This lug suits installers terminating heavy cable to a 1/2 inch stud where a long barrel and brazed seam are specified. It is not for applications requiring insulated coverage or a smaller stud hole. The bare barrel offers no dielectric protection.

UL 467 Listed 600 V Rating

The connector carries a 600 V maximum rating and meets UL 467 grounding and bonding standards. It operates up to 302 degrees Fahrenheit. The 1.42 inch tongue width and 1.12 inch barrel diameter match the 300 kcmil conductor range.

Questions about this item

Should I choose the 300 kcmil or 350 kcmil wire capacity for my project?

The lug accepts wire from 300 kcmil up to 350 kcmil, so select the size that matches your conductor; both fall within the approved range.

What does the 600 V rating mean when the lug is installed?

It indicates the maximum voltage the connection is certified to handle; do not exceed 600 V in the circuit where this lug is used.

How does the 1/2 in stud size limit the termination?

The 1/2 in stud fixes the bolt diameter, so the lug only fits hardware with that exact stud size; verify your bus bar or terminal matches.
