    should be a strip of similar colored metal iirc....so i guess one could site a listing violation, well one good violation deserves another then >



    The Gbar (@ the left) is held in by two 1/4-20's w/locks/flats/stop nuts.

    The bigger wire is a 4/0 feeder, there is a lug kit (unseen) terminating it to the Gbar, a piece of #4 cu is the only ECG running into the panel .

    Definitely sarcasm.

    That is a problem.

    It performs that duty. But without it, the terminal screw ends up working like a guillotine in conjunction with the part shown in the image.

    I somewhat don't have a problem with the GE bar used in your image, if it also has a jumper to the enclosure.

    I use Square D bars in other enclosures all the time, but usually will bolt to the enclosure.

    started a topic How to Properly Ground a Hot Tub (NOT!)

    How to Properly Ground a Hot Tub (NOT!)

    Was asked to remove the 50a GFCI panel that used to feed a (now-long-gone) hot tub. Opened it up and found the unique grounding method of using part of a neutral bar out of a GE panel (the disco is Square D HO) to tie the grounding conductors together.

    The green wire is stripped and under the sheet-metal self-tapper behind the black wire....
