FAQs

The 1031 throat bushing is designed for rigid/IMC conduit with a threaded connection. It supports a 1/2 inch trade size and provides an insulated, secure mounting point within electrical panels, junction boxes, and enclosures. This compatibility ensures dependable performance across standard industrial wiring installations and simplifies replacement when upgrading legacy fittings.
The 1031 is an insulated, threaded throat bushing rated for 105°C operation. Constructed from malleable iron, it maintains structural integrity under typical panel temperatures while preventing electrical contact with enclosure walls. Its insulation helps reduce thermal transfer and minimizes insulation-related failures in normal, non-hazardous locations per NEC/CEC guidelines.
Yes. The 1031 is certified for Ordinary/Non-Hazardous Locations and conforms to NEC/CEC standards, with UL certification for Rigid-IMC use. This makes it appropriate for standard control panels and equipment housings where robust insulation and reliable connectivity are required without specialized hazardous-area ratings.
The 1031 carries NEC/CEC standards and UL certification for Rigid-IMC conduit fittings. These certifications indicate compliance with widely adopted electrical codes and safety requirements in both the US and Canada, reducing regulatory risk for construction and maintenance projects and facilitating supplier qualification during audits and procurement reviews.
Ensure proper alignment and full thread engagement to achieve reliable torque without cross-threading. Use compatible lock nuts or bushings where specified, confirm the 1/2" trade size fits the conduit, and verify enclosure sealing integrity after installation. The combination of insulated construction and UL/NEC/CEC compliance minimizes rework, extends service life, and lowers maintenance costs over the system’s lifetime.
