What are NEIS? National Electrical Installation Standards (NEIS) are the first and only quality and performance standards for electrical construction. They go beyond the minimum safety requirements of the National Electrical Code (NEC) to define what is meant by installing electrical products and systems in a “neat and workmanlike manner.”

    Re: CQD answer published Tuesday, March 24, 2015

    When connecting a metal conduit or cable to a nonmetalic enclosure, the proper term for the fitting would be a "grounding" fitting and not a "bonding" one.

    The simple technique would be to use a grounding locknut. That has a binding screw connection for attaching a "grounding" conductor. A bonding fitting has a pointed screw on the locknut that facilitates bonding of the locknut to the metallic conductive box after locknut is fully tightened. This bonding locknut is used for conduits over certain trade sizes, 1-1/2" from memory so check, and raceways and conduits intervening between load center and hazardous classified areas.
