Hello all,

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?

Thanks.

Yes

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
and ground.
Does the same rules apply to a range?

You can use an existing 3 wire circuit and bond the ground and neutral on
the appliance or install a 4 wire circuit and separate the ground and
neutral on the appliance

If the conductors in the cable are # 10, 8, or 6, you would use a #10
grounding conductor

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
range?

It's a new $800 range with a 4-prong cord so I would rather update the
receptacle if feasible.

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
wall.

250.120(C) Equipment Grounding Conductors Smaller Than 6 AWG.
Equipment grounding conductors smaller than 6 AWG shall be protected
from physical damage by a raceway or cable armor except where run in
hollow spaces of walls or partitions, where not subject to physical
damage, or where protected from physical damage.

Thanks for the info.
