The EATON NBM1 is a plastic grommet boot designed to protect and seal wire or cable entry points in electrical enclosures, panels, and conduit fittings. This type of fitting creates a clean, strain-relieved opening where conductors pass through metal or plastic knockout holes, reducing the risk of insulation abrasion caused by sharp edges. It is typically installed by licensed electricians during panel wiring, junction box assembly, or conduit termination work on both residential and light commercial electrical systems.
The NBM1 grommet boot is suited for use in electrical enclosures where wire entry points require edge protection and a secure, finished fit. It is commonly installed at knockout openings in breaker panels, pull boxes, and similar enclosures during new construction and retrofit wiring projects. Its plastic construction keeps it resistant to corrosion in typical indoor electrical environments.
Designed as an OEM-style replacement or new-installation fitting for standard electrical enclosure knockouts in residential and light commercial wiring applications.
Installation is performed by a licensed electrician. De-energize the enclosure and verify the absence of voltage before working inside any electrical panel or junction box, in accordance with NFPA 70 (NEC) lockout/tagout procedures. Confirm the knockout opening size matches the grommet boot dimensions before installation. Do not install in wet or outdoor locations unless the product is rated for such environments.
