The 10/3 you have is color coded for 220VAC service. Also red,

If you are wanting 110VAC, I woud get 10/3 wire that is color coded for
110VAC, black, white, green & bare. This will eliminate any errors.
You can use any colors you want as long as you know what they are & where
they go electrically. Use the black for hot, the white for neutral, the
bare for ground & cap-off the red. If ur outlet is three pronged & has a
ground screw, you can use the red for the ground prong (red substituting
the for the green wire) , & the bare for the ground screw. If there is no
ground screw, eliminate the bare wire. If you modify the colors, becareful
because it will not be to any code.
