Overview

The ABB H300GR-C is a 3-inch insulated hub with an integrated grounding/locknut designed for threaded rigid metal conduit (RMC). This product ensures secure mechanical and electrical connections in conduit systems, preventing conduit pull-out while maintaining grounding continuity. The insulated throat prevents metal-to-metal contact, reducing the risk of short circuits and corrosion at the entry point. The grounding/locknut feature eliminates the need for separate bonding jumpers, simplifying installation and reducing labor time. Compatible with standard 3-inch threaded RMC, this hub is ideal for electrical distribution systems in industrial, commercial, and institutional applications where code compliance and system integrity are critical. The product meets industry standards for grounding and bonding, ensuring reliable performance in harsh environments. Installation requires no special tools—simply thread the conduit into the hub and tighten the locknut to secure the connection. The insulated throat also provides additional protection against abrasion and vibration, extending the service life of the conduit system. This hub is part of ABB's Installation Products line, known for reliable and durable solutions in electrical infrastructure.
