    push-on grounding clips

    Are the push on grounding clips that can be used for box bonding as required by 250.148(C) listed items?
    If so, does anyone know what UL category covers them?

    These NSI clips have a UL stamp on them.

    They are covered under UL category KDER.

    I thought they would be but when I look up Raco's part number for that clip, it does not show up in the list of part number that they have listed in the category.

    Thanks. However they can't be used in the field as they are UL Recognized and not UL listed.

    I note they carry the “Listed” rather than “Recognized” UL mark on the clip itself.

    It may be both listed and recognized.

    It does not appear on the list of their products that are listed under that category.

    That is interesting as that part number is not on the list of UL listed parts under KDER.

    why don't you ask them?

    My guess is that it would be covered under option 7 in 250.8

    250.8 Connection of Grounding and Bonding Equipment.
    (A) Permitted Methods. Equipment grounding conductors,
    grounding electrode conductors, and bonding jumpers shall be
    connected by one or more of the following means:
    (1) Listed pressure connectors
    (2) Terminal bars
    (3) Pressure connectors listed as grounding and bonding
    equipment
    (4) Exothermic welding process
    (5) Machine screw-type fasteners that engage not less than
    two threads or are secured with a nut
    (6) Thread-forming machine screws that engage not less than
    two threads in the enclosure
    (7) Connections that are part of a listed assembly
    (8) Other listed means
    Listed assemblies can include assemblies that are field assembled. In any case, the code does not require ground screws to be listed, or terminal bars for that matter.
    Bob
