FAQs
LT50S is designed for straight FMC conduit and 1/2 inch trade size. When installing, ensure proper alignment with the conduit run, tighten to the manufacturer’s torque specification, and confirm a secure seal at the enclosure. Use appropriate sealant or gaskets if required by the application and verify ingress protection after assembly to maintain hazardous-location integrity.
LT50S carries NEC/CEC compliance with NEC hazardous ratings including Class I, Division 2, Class II, Division 1 and 2, and Class III, as well as area classifications for hazardous/classified locations. This enables safe operation in chemical plants, oil and gas environments, and other high-risk industrial areas, supported by UL certification pages.
Yes. With hazardous/classified location ratings and a robust steel construction, LT50S is well-suited for chemical processing, refining, and oil and gas facilities. Its straight, 1/2" FMC configuration simplifies routing in tight spaces while maintaining compliance with NEC/CEC standards and UL-listed expectations for harsh environments.
LT50S uses a non-insulated metal body designed for direct terminations with FMC. Grounding should follow standard plant practices for metallic liquidtight fittings, ensuring a continuous ground path where required. The non-insulated design reduces thermal resistance and simplifies enclosure bonding where applicable, while maintaining safe operation in hazardous locations.
The LT50S provides durable steel construction with certified hazardous-location ratings, reducing replacement frequency and maintenance intervals. Its 1/2" size and straight geometry speed up installation, lowering labor costs. Overall, you gain predictable performance, reduced downtime, and a favorable total cost of ownership in demanding industrial environments.
