SKU CH-SP5M-1NGHX

One-hole compression lug for 250–300 kcmil copper wire, 1/2 in stud, long barrel, 600 V, tin-plated, UL 467 listed

  • Product typeElectrical Connectors
  • Rated for 600 V maximum voltage
  • Withstands 302 °F operating temperature
  • Brazed barrel ensures strong crimp connection
  • Tin-plated copper contact resists corrosion
  • UL 467 listed for grounding applications

One-Hole Compression Lug 250 kcmil

This one-hole compression lug accepts copper conductors from 250 kcmil up to 300 kcmil and terminates on a 1/2 in stud. The brazed barrel and tin-plated copper contact provide a secure crimp connection rated for 600 V. It meets UL 467 for grounding and bonding applications.

Long Barrel 0.95 in Depth

The long barrel measures 0.95 in and has an outside diameter of 1 in, giving extra crimp area for sustained mechanical and electrical loading. Bare copper with tin finish resists oxidation at continuous operating temperatures up to 302 °F. Tongue width of 1.18 in distributes clamping force evenly across the stud.

Upgrade from Standard Barrel Lugs

Installers moving from standard-barrel lugs gain the longer 0.95 in barrel for improved pull-out strength on heavy-gauge feeder cables. The jump is worth it when vibration, thermal cycling or high fault-current duty demand the added crimp length and brazed-seam integrity.

Questions about this item

Does the 302 °F temperature rating mean the lug stays cool under continuous 600 V load?

The lug is rated for a maximum operating temperature of 302 °F and a maximum voltage of 600 V; it does not generate heat itself but will reach the temperature of the conductor carrying the current.

What crimp tool and die are required to terminate 250 kcmil wire in this lug?

A hydraulic crimp tool with a die set approved for 250–300 kcmil copper and the lug’s 0.95 in barrel length is needed; the lug uses a brazed barrel style and tin-plated copper contact.

Will the 1.18 in tongue width fit the existing 1/2 in stud pattern on my bus bar?

Yes, the lug is built for a 1/2 in stud and has a tongue width of 1.18 in, matching standard 1/2 in hardware patterns.
