I need to convert a 50A 3-prong range receptacle to a 4-prong range
receptacle, so I need to run a 50' ground wire from the receptacle to
the ground buss. Can anyone tell me what size ground wire to use? Is
it the same size as the conductors?
I know if you buy a new electric dryer, you can either put a 3 prong
cord plug on and tie the neutral and groung together, or you can
convert the outlet to a 4 prong outlet and tie together the neutral
Does the same rules apply to a range?

I believe that you will need to run a new 4 conductor cable as I think it
is against code to run a separate wire outside the outside layer of a
bundle of wires. In other words, one cannot create a 12/3 with ground out
of 12/2 and a separate wire. You need to run a full 12/3 cable. I had to
change out such a wire when we built our house.
Why do you need to convert it? Why can't you use a 3-prong cable from the

In a replacement scenario you can usually run a separate wire for the
ground as long is it is protected from damage or fished through a

hollow spaces of walls or partitions, where not subject to physical
