Wall outlet problem

Alright im doing some electrical work around the house changing plugs and all. And i pull a plug from the wall that has never worked before. And i know the plug is on a double braker (220).

So i started messing eith the plug. I have 3 wires (red,black,white). If i only plug the white and the red wire the plug works i get 110v. If i plug the black and the red wire i get 220v. If i plug all 3 my braker jumps. What im trying to figure out is! Is it safe to keep the white and red wire plugged on my outlet and just cap and tape the black wire all in the same box?

Receptacles have different configuration configurations based on voltage and ampacity. They are not interchangeable.

What are you trying to do?

No, nominal voltage is 240.
I have 3 wires (red,black,white)
Is this cable or conduit? If cable is there no ground wire?
If i plug the black and the red wire i get 220v.
Should be ~240 volts. What is the voltage from black to white and red to white?
