Stove wiring - 3 wires in wall no red
 
Hi,
I am moving into a house that had a dryer outlet where the stove is supposed to go. As far as I know no dryer was ever installed there. The double breaker is 60 amp.

I removed the outlet cover and found 3 wires : white, black , bare, but no red!

How do I make it work so I can plug my stove?

(The stove is a newer one and has a 4 prong cord , but I can change that if needed)

Thanks for your help!

The only way to properly wire this for the stove is to replace the wiring with 6/3 w/g cable and replace the breaker with a 50A. (Alternatively you could use 8/3 and 40A). The white/black/bare has never been an acceptable way to wire a stove (or dryer).

What is the neutral wire there for in 4-wire installs?

It returns the neutral current from the control circuits and light bulbs.

Gotcha so it basically provides the appliance with 240v and 120v...

Dryers and ranges are rated 120/240. That is why you have a neutral. Even though the range may operate without one, it is required in NEW installations.

Your dryer must be on a 30 amp breaker. The existing wire is technically not proper for a range or a dryer. Type SE cable has a bare ground/neutral and is acceptable. Type NM is just about the same thing but its not legal.

Personally, if it was in my place, I wouldn't hesitate to use it. If I was doing any renovation work, I would replace it and make it legal.

If you do change to a 3 wire pigtail on your range, be sure the bonding strap in in place. It ties the center terminal (the bare neutral/ground) to the metal frame.

In new installations.

Existing can use the 3 wire system.

Except the fact that the bare neutral in type SE cable is the same size (or almost) as the circuit conductors.

True but, how much current does it carry?

To me, the dangerous part is the possibility of the appliance carrying current if the neutral/ground opens. That could happen with any 3wire installation.
