  • Crimp termination suits 4/0 AWG wire

Burndy 4/0 AWG Compression Terminal

The Burndy YAD28M20E34 is an uninsulated copper compression terminal built for 4/0 AWG conductors. It suits electrical contractors and maintenance teams terminating heavy-gauge wire in panel, motor and grounding applications.

302 °F rating with 600 V capacity

The bare copper barrel accepts a single 4/0 AWG wire and carries a maximum operating temperature of 302 degrees Fahrenheit at 600 volts. Tin-plated contact surfaces resist oxidation while the brazed barrel maintains mechanical integrity under load.

Replaces worn or undersized lugs

This terminal upgrades connections where factory lugs have corroded, loosened or cannot accept 4/0 AWG conductors. The jump is justified when a UL 467 listed, long-barrel design is required for code compliance or vibration-prone environments.

Questions about this item

How do I install the YAD28M20E34 terminal, and which crimp step is often missed?

Strip the 4/0 AWG conductor to match the 0.87 in barrel length, insert fully into the brazed copper barrel, and use a UL 467 listed crimp tool with the correct die for 4/0 AWG; the step most often missed is verifying full insertion before crimping.

What maintenance or replacement will this compression terminal need over time?

Inspect the tin-plated copper contact for oxidation or mechanical loosening after thermal cycles; re-torque the 3/4 in stud hardware if vibration is present, and replace the terminal if the barrel shows cracking or the tin finish is worn through.

What is the first limit reached under sustained heavy current?

The 302 °F maximum operating temperature is the first limit; continuous loading that drives the connection above this temperature degrades the tin plating and reduces clamping force on the 3/4 in stud.
