Overview

The ABB H300GRA-C is a 3-inch aluminum hub designed for threaded rigid metal conduit systems, featuring an integrated grounding/bonding locknut and insulated throat. This hub is part of the H300GRA series, optimized for secure electrical installations where conduit termination and grounding are critical. The aluminum construction ensures corrosion resistance and durability in industrial environments, while the grounding locknut provides a reliable electrical bond without additional components. The insulated throat prevents abrasion and protects conductor insulation during installation, reducing the risk of damage. This hub is ideal for commercial, industrial, and utility applications requiring compliance with NEC and OSHA grounding standards. The 3-inch size accommodates standard rigid metal conduit, ensuring compatibility with existing infrastructure. The grounding locknut eliminates the need for separate bonding jumpers, streamlining installation and reducing labor costs. The insulated throat design maintains conductor integrity, minimizing the potential for shorts or ground faults. This product is manufactured by ABB Installation Products, a trusted name in electrical infrastructure solutions.
