My apologies to folks who answered my prior post. Stove is new unit
and I have not pulled old unit yet as replacement is for cosmetic
purposes prior to house sale. I found install manual inside of
covered drip pan and have hook up directions. Gives both 3 & 4 wire
methods. Wires are in metal sheathing coming out of stove, & labeled
as 10 gage and are copper.

Seems like for current code (?) I will have to run 4-wire cable unless
I can get along with a separate appliance ground wire. Length of run
will be 30-35 feet so can I use 8 gage wire if separate run is not
allowed?

For current code, you would have to run a new 4-wire cable. But if you
don't mess with the old wires, you don't have to meet the current code.
Your old wires met the code requirements when they were installed and
you can reuse them for the new stove.

You never said what the amps requirement is for the new stove; probably
40A. My code book is at work, but I think (if you really want to run a
new cable) you can use #8 copper cable if it is rated 75°C, or you could
use #6 aluminum SER. Eight gauge wire is a lot easier to work with than
#6 because #8 is much more flexible (it has small strands.)

I would just install the new stove on the old 3-wire circuit and be done
with it. You're trying to make this more difficult than it is. :-)

Best regards,
