    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.

    Red and black to the prongs that are alike or opposed. Bare to the odd prong or centered.
