FAQs
To install the 1040NI, verify the catalog number and ensure your enclosure knockout matches a 4" trade size. Thread the bushing into the enclosure opening until snug, using appropriate torque for metal-to-metal connections. Confirm the conduit is properly seated and alignment is correct to prevent binding or cross-threading, then complete the installation with standard conduit fittings for a secure seal.
1040NI is designed for ordinary/non-hazardous locations and adheres to NEC/CEC conduit standards, simplifying code qualification. Its rigid/IMC compatibility and threaded design support reliable, code-compliant assemblies. For procurement and verification, reference Eaton’s datasheets and the provided NEC/CEC compliance documentation.
Yes, the 1040NI is specified for ordinary/non-hazardous locations.
