    As long as the splicing connector is listed for the combination of wires spliced-compliant.

    The consensus is that it is legal for all of US to do it, we never said YOU were allowed to do it also....

    EGC under one lug

    I often see in older panels all of the EGCs terminated under one large lug. What is the history or acceptance of this practice?

    Not legal now, wasn’t legal then. Not listed for all those small conductors.

    Some ground buses are listed for two EGC wires, but is about as good as it gets. Some weird terminals may accept three.

    Not legal but likely not a hazard either if they're twisted neatly and terminated in a proper sized lug.

    I use a lot of troffs above panels , make a nice 20 pos G bar w/ lug in them, elevate it above the troff 'lip ' with 1/4-20 hardware. I'll use 2 or 3 2" nipples troff to panel....There's only one (usually #4 bare cu ) running into my panels

    It's a 1/3 less messy

    Touche. You almost had me arguing with you there.

    Be honest. You don't want to do that with a ground bus. You want to do it with a lay-in lug because you forgot to pick up a ground bar that morning. Or maybe you want to use just a green screw.
