Old Stove Wiring (Hot/Neutral/Ground) ??

Hello and Thanks in Advance! I am replacing an old stove and it only has three wires (not/neutral/ground or black/white/bare). After lots of searching, I have not found out how to connect the new stove which requires two hots. My house was built in 1955. It is 240V on a 50 amp breaker.

Any suggestions on how I can hook up the new stove?

Almost certainly the white is a hot also. The bare is serving as a combined ground neutral. If it is on a two pole breaker that is what you have. You can either convert the stove to 3-wire or best practice run a new 3-wire+ground cable (6-3Nm-b). What size wire in the existing cable? What Size breaker? What is the stoves full load amps?

I agree with Ray, you have two hots and a combination neutral/ground.

Great. Yes, it is a double pole breaker (40 amp, not 50 amp like I stated before). It is difficult to size the wire by eye as it is copper stranded.

If I do not run new wire, how do I hook it up to a 3 wire plug? White and black on the hots and put the bare on the neutral?

As Ray asked,
What is the stoves full load amps?
And, what size breaker does the instruction sheet for your new stove specify?
