Burndy YAD30M16E58 One-Hole Compression Lug 250 kcmil 5/8 in Stud Long

Burndy YAD30M16E58 One-Hole Compression Lug

The Burndy YAD30M16E58 is a one-hole compression lug designed for 250 kcmil to 300 kcmil copper conductors with a 5/8 in stud size. It suits electrical contractors and industrial maintenance teams who need a reliable crimp termination for heavy-gauge wire in panels, switchgear or motor leads. The long barrel provides extra crimp area for secure mechanical and electrical connection. Tin-plated copper construction resists corrosion in demanding environments.

Sustained-load performance

Rated for 600 V and a maximum operating temperature of 302 °F, the lug maintains conductivity under continuous full-load current without overheating. The brazed barrel seam prevents splitting during repeated thermal cycling, while the tin finish minimises contact resistance over time. Crimp termination creates a gas-tight joint that does not loosen under vibration or thermal expansion. The bare-metal design allows visual inspection of the crimp quality after installation.

Upgrade context

This lug replaces mechanical set-screw connectors that can loosen under vibration or thermal cycling in heavy-duty circuits. The jump is worth it when code or specification requires a compression termination listed to UL 467 for grounding and bonding applications. It is not suited for aluminium conductors or for installations where a two-hole NEMA pad is required for busbar mounting. Buyers needing a smaller wire range or a different stud size should select the matching Burndy lug for that specification.
