Burndy

Burndy YAD28M8E516 4/0 AWG 5/16 in Stud Terminal

SKU CH-5XFY-RF26T

Uninsulated copper crimp terminal for 4/0 AWG wire with a 5/16 in stud hole, rated to 600 V and 302 °F

  • TypeElectrical Connectors
  • Designed for 4/0 AWG conductors with a 5/16 in stud hole
  • Brazed barrel construction resists splitting under high compression loads
  • Tin-plated copper contact delivers low-resistance connections up to 600 V
  • Long barrel length of .87 in provides ample crimp area for secure terminations
  • UL 467 listed for grounding and bonding applications

Uninsulated Compression Terminal

This BURNDY YAD28M8E516 terminal connects 4/0 AWG copper conductors in industrial and automotive electrical systems. The bare copper barrel with tin finish accepts a single wire size and secures to a 5/16 inch stud for reliable power distribution.

Crimp Termination at 600 V Maximum

The connector is rated for 600 volts and a maximum operating temperature of 302 degrees F. UL 467 listing covers the crimp-style termination, while the brazed barrel construction maintains integrity through the long barrel length of 0.87 in and outside diameter of 0.89 in.

Direct Crimp Installation

No insulation strips back, so the conductor seats directly into the bare barrel for a standard compression crimp. The 0.95 in tongue width aligns with the stud hole, and the brazed seam resists splitting during compression. Installers must use the correct die for 4/0 AWG to avoid loose connections.

Questions about this item

Should I choose the 4/0 AWG version or a smaller gauge for my cable?

This terminal only accepts 4/0 AWG conductors; the minimum and maximum wire size are both 4/0 AWG, so a smaller gauge will not fit.

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

The 600 V maximum voltage is the highest potential the copper barrel and tin-plated contact can safely carry once crimped and bolted to a 5/16 in stud.

Does the UL 467 listing cover the crimp connection or only the stud mounting?

UL 467 applies to the complete assembly — brazed barrel, tin-plated copper contact and 5/16 in stud hole — when crimped with the correct tooling.
