FAQs
For non-armoured tray cable installations, use the 1in NPT threaded gland on a steel body. Ensure enclosure openings match the gland size, apply a suitable gasket or sealing compound as specified by Eaton, and follow IF 1826 instructions to torque the gland properly so the seal engages evenly and maintains ingress protection. Verify diameter and compatibility before assembly.
Yes. The CGB3911 carries a NEMA rating of 3R, which supports outdoor and damp installations in ordinary locations, as long as the environment remains non-hazardous. It aligns with NEC/CEC requirements for general-purpose glands, reducing regulatory risk. Always confirm site conditions, enclosure IP expectations, and any additional local standards that may affect seal integrity.
The cable range of 1.188–1.375 inches allows use with non-armoured tray cables within this window. For a tight seal, verify the outer jacket diameter and ensure the gland threads engage fully. When in doubt, select the closest fit inside the range and test a mock assembly to confirm a tight seal.
CGB3911 is designed to NEC/CEC compliant installations and carries a NEMA rating of 3R. It supports ordinary/non-hazardous locations and should be used in general-purpose gland applications for tray cables in control panels and enclosures per applicable codes. Always verify local code requirements for your application.
You can access IF 1826 installation sheets for CGB connectors and Eaton's CGB3911 specification sheet on Eaton's website. Catalog pages for non-armoured glands provide additional application notes, mounting torque, seal seating, and compatibility with tray cables. These resources help ensure correct installation, regulatory compliance, and faster procurement for panel builds.
