EverLink Patented Technology

PowerPact B-frame devices feature EverLink lugs, a new cable connection method with wire creep-compensating technology built directly into the lug. This standard lug option minimizes loose wiring caused by wire strand deformation, vibration, and shocks.
The patented design maintains low-resistance connections for continuity of service, even with fine stranded conductors.
  • Reduce the loosening of cables over time using a spring tension design
  • Rated for bare use with fine-stranded conductors up to Class K
  • Available with unique integrated control wire terminals
