Can I link neutral from a 110v wire or receptacle to a 220v 3 wire to create a 4 wire oven range outlet?

Would the physics work? Yes. Is it code compliant and safe? No. It's not permissible under code to use any conductor from one circuit on another. Besides creating weird wiring that would be hard to follow and debug, it's a safety issue. You prepare to work on one circuit, turn off the breaker for that circuit, verifie that it appears off and proceed to work on it. Later some appliance goes on automatically or someone closes a switch to turn on a light and suddenly the neutral on the circuit that's supposed to be off and that you're working on is energized. Even if you were to do it, the neutral would have to be of the same or greater ampacity as the

I would find the install manual for this oven. Many 240V appliances, eg dryers, are designed so that they can use either a 4 wire or 3 wire cord. The older 3 wire receptacles are no longer permitted for new installs, but existing ones are grandfathered and widely used. Converting your receptacle to that, while not code compliant either, would at least be logical and conform to older wiring that's still out there. That would work if the oven supports using either a 4 wire or 3 wire cord.

I'd say no. You need four wires running back to the breaker box. Two hot, a neutral, and an equipment ground. The other issue might be wire sizing. How many amps does that oven draw? Can you change the range to a three wire? That would depend on whether the neutral on the range does something now. Is there a timer, light or something else that depends on 115 instead of 240? I don't know if it violates code to do the conversion. There might be a provision specifically saying not to alter things.

shop has 110v and 220v ... but of course the 220v is only three wire. It makes sense to me that I could use the neutral from the 110 to create a 4 wire 220v range outlet. But I hate electrons so someone please confirm or deny this. THANKS!

Short answer HELL NO.

When you have to ask a simple thing like this you need to get an electrician involved.

Now for the explination. Years ago most 220/240 volt items would have 3 wires. The two hot wires and a neutral. Usually the neutral was bonded to the frame of the device and used with one leg of the 220 volts to supply 110 v such as a timer on an oven or the light.

Modern wiring code requires 4 wires. The neutral is not connected to the frame of the device, but the 4th wire is the safety ground and is connected to the frame.

So for your oven you look at the wiring , find the neutral and connect it to the frame. Then you have the 3 wires to match your receptical.

What does the oven do with the neutral? If it is just a timer or a light and you can live without it (mechanical controls, not touch pad) , don't connect the neutral. That is the safest thing. You can even get 240v lamps if it is just a light and you want it. (minor rewire in the oven). The problem with setting the way back machine to the early

Might ber POSSIBLE but not legal - and dubious safety
