Burndy YAD27M8E516 compression lug 3/0 AWG 5/16 in stud long

SKU CH-G23K-QMKR5

A one-hole compression lug for 3/0 AWG wire with a 5/16 in stud and long barrel, rated to 600 V and 302 °F

  • TypeElectrical Connectors
  • UL 467 listed for reliable grounding
  • Tin-plated copper resists corrosion
  • Long brazed barrel gives strong crimp
  • 600 V rating suits many circuits
  • 302 °F max temperature for tough environments

One-hole compression lug for 3/0 AWG

The Burndy YAD27M8E516 is a copper compression lug designed for terminating 3/0 AWG conductors in electrical and industrial wiring applications. Its long barrel style provides extended crimp area for secure connections. The lug accepts a 5/16 inch stud for mounting to busbars or equipment terminals. It is supplied new and ready for installation.

Tin-plated copper barrel rated to 600 V

The barrel is constructed from copper with a tin contact finish and measures 0.79 in outside diameter and 0.79 in length. It meets UL 467 standards for grounding and bonding applications. The termination style is crimp only and the maximum operating temperature is 302 degrees F. The tongue width is 0.99 in for the single mounting hole.

Brazed barrel construction for heat resistance

The brazed barrel style maintains integrity under the 302 degree F maximum operating temperature without insulation to degrade. Bare copper with tin plating conducts heat away from the crimp joint during normal load cycles. No moving parts or cooling requirements exist for this passive connector. Compatible Grainger references are 22P219 and 22P221 for cross-reference purposes.

Questions about this item

What does the 3/0 AWG rating mean when the lug is installed in a real circuit?

It means the lug accepts a single 3/0 AWG copper conductor, crimped into the long brazed barrel for a secure connection rated to 600 V and 302 °F.

Which standard governs the 5/16 in stud interface and what does it limit in practice?

UL 467 covers the compression lug, limiting use to copper wire sizes up to 3/0 AWG at 600 V maximum with a 5/16 in stud hole.

What physical dimensions determine whether this lug fits my bus bar or terminal block?

The tongue width is 0.99 in, barrel length 0.79 in, and barrel outside diameter 0.79 in, so the mounting surface must accommodate those measurements.
