Eaton H1038 Throat Bushing - Insulated Rigid/IMC NEC/CEC
Part Number: H1038
Quick Summary
Eaton Crouse-Hinds throat bushing provides a secure, insulated threaded connection for rigid/IMC conduit in electrical enclosures. In tight panels and busy installations, ensuring a reliable seal and consistent termination can be challenging, especially at elevated temperatures. This product aligns with NEC/CEC standards and UL certifications for rigid IMC use, with an Ordinary/Non-Hazardous area classification to support general-purpose installations. Its combination of insulation, a 150°C rating, and a compact 3" trade size drives faster, compliant installations while reducing rework. Selecting this bushing translates to lower maintenance costs, safer terminations, and predictable procurement for mid- to large-scale industrial projects.

FAQs
Power down equipment and prepare the enclosure. Insert the H1038 into the appropriate threaded opening, ensuring the conduit threads engage cleanly. Tighten to the manufacturer's guidelines with standard thread sealant if required, verify the insulation remains intact, and confirm proper seating and alignment before energizing. This reduces leakage paths and improves termination reliability in ordinary locations.
Yes. The H1038 is designed to meet NEC/CEC standards and is UL-certified for rigid-IMC conduit in ordinary/non-hazardous locations. Its insulated, threaded design with a 3" trade size and 150°C rating supports compliant terminations across US and Canada electrical installations, helping streamline inspections and approvals.
Key specifications include a 3" trade size, threaded connection, insulated design, malleable iron body, and a 150°C temperature rating. It is built for rigid/IMC conduit, with dimensions of 2.1 in length, 1.1 in width, and 0.8 in height, weighing 0.02 lb. UPC is 784564112972, with NEC/CEC compliance and UL certification.
Yes. The insulated, threaded design provides durable terminations that resist thermal degradation and arcing, while NEC/CEC and UL certifications minimize inspection issues. The compact form and reliable material reduce rework, enabling faster commissioning and lower lifecycle maintenance in general-purpose facilities.
