220 range outlet
i am changing a 220v outlet for a range, 3-wire , wiring already in place, everywhere i look it says one red , one white, one black, i have 2-blacks & a white, my question is, i know where the white goes of course, does it matter which black goes to which side? I dont think so i just want to make sure, they both should be hot, so it shouldn't matter right! I work with 110v all the time, never with 220v. If some one knows i would appreciate it!! Thanks!

each black should be 110v with the white and it shouldn't matter which leg goes on which side.
use a voltmeter to test if unsure.

Each black wire should read ~120V between it and the neutral, and ~240V between the 2 black wires. Coloring one of the black wires to Red is just for visual identification (on a 120/240V 1ph system). Color identification becomes important when dealing with 3ph systems.

At least you don't have a black, white and ground that seems to be commonly discussed on this forum. You have four wires and thats all that matters. However, it is unusual to see a cable colored like that. What does it say on the cable jacket? What type of cable do you have?

What type of cable do you have?
I'm guessing conduit.
