Hubbell HYH3931 Grounding and Bonding, H-Tap, Copper, 750MCM-250, Yellow, Index K-R

Ensure reliable, code-compliant grounding on every install with the Hubbell Premise Wiring HYH3931 Compression H-Tap. Engineered to create an irreversible, low-resistance bond for 750MCM–250 conductors, this copper H-Tap delivers consistent conductivity that minimizes voltage drop and protects sensitive equipment in security, surveillance, monitoring and networking power systems. The die index feature confirms the correct crimp die was used—reducing rework and helping meet inspection requirements—while the bright yellow finish and K-R index simplify visual identification and inventory control on busy job sites. Sized for heavy-gauge applications and built from corrosion-resistant copper, the HYH3931 supports long service life in indoor and protected outdoor enclosures. Ideal for electrical contractors, integrators and facility managers who need dependable grounding and bonding components for power accessories and parts, this H-Tap installs quickly and stays secure under vibration and load. Specify the Hubbell HYH3931 for critical grounding points in security and surveillance deployments or add it to your next grounding kit to improve installation speed and system reliability.
