    Why does my 8 3 wire with ground have a bare coper wire
    I am installing a range with 8/3 with a ground it has a red-black for hot white for nutral, green for equipment ground bar and a bare copper wire ground. The receptical has red/black/green/white but no place for the bare wire to hook to. Should I cut this off or hook it to the green

    Well, if you have a red, a black, a white, and a green... it's not 8/3... it's 8/4

    Thanks your right but I still can't figure what to do with the extra bare ground as the green is gounded at the receptical and will be grounded at the bar

    What type of wire are you using? There are some wires that are classified for "tray" use which have a bare wire incorporated into the skin of the cable.

    Nmb8/3wg is what the invoice says it's in a rubber type sheath has 4solid coper coated and one bare all in rubber sheet. I would guess for safety I should just connect to the green ground as they will go to same place on my bus bar only one bus bar in my 100amp box nuetral and ground are connected to it

    Okay,

    I posted to this thread yesterday but it's not here.

    Question, is there a yellow line on the green conductor?

    If there is one, then you may have a cable that is designed for use as a isolated ground.

    It is the wrong type of cable for a range.
