50 amp outlet in a detatched garage
i am wiring my detatched garage for an arc welder and need a 50 amp outlet....
it's allready been wired from the house to the garage...a subpanel is in (correctly) in the garage
my question is in regard go grounding the oulet
i am running 6 gaure four wire (red,black, white, ground)from the subpanel to the oulet
it's my understanding that the white wire is the"ground" in this application...my subpanel is fed by 4 wires, and the GROUND BAR AND WHITE BAR/BUSES are seperated
now here's the question...if the ground bus and white bus are seperated in the subpanel...how can the white wire act as a ground?....and what do i do with the ground wire?
thanks for the help
