I had an electric wall heater with a dedicated circuit. It is 220 volt. The old fan was hardwired. I'm replacing the fan and am considering putting in a 220 volt outlet. The cable is 12/2 with black and neutral both hot. How would this be wired to the outlet? I've attached a photo from a site and as you can see the 220 volt setup is 12/3 cable. Can I put in a 220 outlet with just 12/2?
You need to do a bit more research to educate yourself - no offense meant. I mean that you need to get a better understanding of 120v compared to 240 volt and 120/240 devices.
Biggest misconception of many DIYers is that if a wire is "white" it is a neutral. This is incorrect especially in your case as you lay out the logic.
You can't just use any receptacle/outlet you want to use and repurpose it. Receptacles have a confuguration based on the voltage and amperage what what the circuit will be utilized as and how it is set up in the way of what gauge wire to be used and over current device (breaker amperage). The different configurations are purposely done to prevent you from plugging in a device into a receptacle that does not match the same voltage and amperage. It is a security feature in a sense of the word.
I'm trying to figure out how to do a grid interconnect with a hybrid inverter. I can get things to work electrically, but I'm having problems getting the job done in a code compliant method.
Currently the utility feed comes up through a cement floor into an inside wall to the garage as 4/0 Al in PVC conduit. We have an 11kW Generac and the ATS is the first box in line. The output of the ATS then goes vertically into the bottom of the main service panel. When that wall was finished, the drywall crew built a false wall to cover the electrical components, the main service panel and ATS are flush mounted in the false wall.
The hybrid inverter accepts the generator output and does the 2 wire start function. So I will be removing the ATS. I'm considering using interior and exterior gutters to help route wiring. I don't have enough wall space inside the garage, so some of the equipment will have to be mounted on the garage wall exterior.
The wall cavity is 3.5" deep and 13" wide. I can't figure out a code compliant way of getting the service conductors into the exterior gutter without violating some part of Articles 312, 314 or 376 of NEC 2020. I've been hung up on this aspect for several days.
Anyone have any ideas that would work?
Thanks,

I have an outlet that isn’t working. I pulled it out. I have two black, two white wires and a ground. Plugged in my tester and the two lights indicating correct lit up. I hit it with a multimeter and nothing . . . . so something was powering to get the tester to light up. When I use my probes to black and ground, I get 120v. This place has always baffled me with the electrical. What the heck is going on here? How do I remedy? Both black wires are hot.
