Are you changing the stove/range as well? If so, size it based on what
The wire sizing isn't based on the number of conductors so use the same
as is there if the requirements haven't changed.
In general rule of thumb, the range will be on a 50A breaker and 8 ga
So the real answer is "we don't know" w/o additional information on the
range and breaker/fuse on the circuit.

replacing the appliance, so this is a bit strange. The
appliance install instructions should say what to use.

By NEC except for the lowest-possible rated temperature rating cable

50 A by my copy of the Tables. I don't recall ever seeing #6 just for a
range altho I suppose some of the newer double ovens and all the bells
and whistles might have >50 A demands...
1. Determine the load in amps.
2. Select a cable to handle the amps.
3. Select a breaker to limit amperage and protect the cable.
4. Up-size the cable if the permissible voltage drop would be exceeded.
If it is a double oven stove or a stove with a warming drawer you need number 6 copper wire.
If it is a basic stove you can get by with #8 copper.
The best thing is to check the stove installation instructions or the nameplate.
recommended to put the #6 cable in when replacing old cable to upgrade
to "current code". It would be a pitty to have to do the job all over
again next time you buy a new stove just because you "cheaped out"

Probably got a stove that has 110v circuit in it as well as 220. Some newe
r stoves with electronics often do that. Not sure why since they could jus

20. In any case they probably need a 4 wire circuit and I'd go with #6 jus

NEw ovens typically have installation intructions for hard wiring it in to
either a 3 wire or 4 wire installation. Every install manual I've seen
covers wiring it in direct to 3 wire, if that's what's there. Given that
the installation instructions specifically cover it, AFAIK, it's code compl
iant and you're not required to run new wiring back to the panel.

Stoves have had 120V available on a 3 wire cord for 50+ years. You
have the two hots, the third wire serves as both the neutral and the
ground. It's permitted to carry current, that gives you 120V. And it's
very common for stoves to have lights, receptacles to plug a coffe pot in,
etc that are 120V. Stoves back in the 50s had them.
What's different with 4 wires is that adds a separate dedicated ground,
which doesn't carry current, instead of sharing the neutral as the ground,
as is done with 3 wires.

Some inspectors will consider a hardwired appliance a change to the wiring
and require you to upgrade to code. Not all but some.
Sure, they ran the analog clocks on 110 you used to see in the middle of th

Maybe some inspector, somewhere will, but it's obviously the exception,
otherwise all the manufacturers of ovens and stoves would not include
instructions on how to wire the appliance into either 3 wire or 4 wire.
If it was a code violation or not acceptable to most inspectors,
it would be totally irresponsible.
