Thomas & Betts H250GR-TB Grounding Conduit Hub

The Thomas & Betts H250GR-TB Grounding Conduit Hub provides a watertight, electrically bonded termination between 2-1/2 in threaded rigid metal conduit (RMC) or intermediate metal conduit (IMC) and threadless electrical enclosures, ideal for panelboards, switchgear, motor control centers, outdoor enclosures, and hazardous-location equipment where secure conduit termination and environmental sealing are required. Constructed with a die-cast zinc hub and locknut, it includes a molded thermoplastic throat rated to 105°C (UL 94 V-0) and an embedded nitrile (BUNA-N) sealing ring to protect conductors from abrasion while resisting moisture ingress. The hub uses a threaded NPT connection, supports a 2-1/2 in trade size, and features a throat diameter of 2-13/32 in with a maximum panel thickness of 1/4 in. Compatible with RMC and IMC, this grounding conduit hub delivers a reliable grounding path and durable environmental protection in commercial and industrial power-distribution installations. It is UL Listed (E23018) and CSA Certified, with RoHS3 and REACH compliance, making it suitable for installations in power distribution equipment, industrial machinery, and outdoor electrical systems requiring a robust, code-compliant grounding solution.
