how do i hook up my new 3 prong 220 receptacle that was once hardwired. a black, red and bare wire in the box?

As Sam Said, Black and Red wires are
"phase` or "hot` wires and go the the brass
screws on your new receptacle.
The bare wire goes to the green 'ground` screw.
If you've got a white, (silver), screw, you've got the wrong receptacle for the wiring you've got.Source(s): Retired Electrical Consultant.

Red and black to the prongs that are alike or opposed. Bare to the odd prong or centered.Source(s): I'm a real electrician

black and red wires are hot ---be careful. the bare is a ground. shouldn't you have a neutral in the system...unless...
