    Ground wire to Hot tub
    When I hook up the ground wire to the bar on the hot tub it trips the GFI but when I run it without the ground its runs but gives a little shock when you come in contact with a object outside the tub. I dubble checked the wireing from the main to the GFI and it is wired to spec, is there a fult with the mother board on the hot tub that keeps the ground from being hooked up. Bill

    My guess is you have an actual ground fault within the spa. The GFI is sensing this fault, and doing what it was designed to do. The comment about "getting a little shock" is of great concern. Electricity and water are a very poor combination at best. You need to shut this spa down and have it repaired before someone is injured or killed.

    I agree with poolman, this is dangerous. We can't diagnois the fault from here and I thnk you need a hot tub repair person or an electrician

    Hello there. I do repair and install spa's. From my experience, when it is the ground wire tripping the GFI usually the problem is with the GFI itself. Is it a manufactures GFI, if so replace the unit with a higher load capacity. With the shock problem, check your insulation at every connection. A motherboard would not cause this problem when properly insulated.

    Just keep in mind you are playing "You bet your Life" so how you handle this is certainly your choice. If you are not comfortable with changing out the GFCI and checking all the wire connections, I would pay a professional to do this for you.

    I tested the gfi and it works,it is working the way it should, when I said a little shock , what I mean is its like when u rub your feet on a rug. It did not always do this. I evan try a ground rod stright to the tub and it still trips.

    IT calls for a dubble 50 so should I try a higher load, I was thinging that the span is 100 to 120 FT and that the ground may be to small
