12/2 vs. 12/3

I'm doing a wiring project and need some advice on what type of wire to purchase. I'm basically going to tap into an existing 20 amp circuit outlet in the kitchen to install an extra outlet. I need to do this as I am moving the refridgerator and installing an over the range microwave.

The cost of the wire is not a concern for me. My basic question is if I can just buy 12/3 wire, even though I probably won't need the extra hot wire? Can I do this and just not use the extra hot wire?

Also, for what I am doing will 12/2 wire be enough? Actually, I'm pretty sure that it will be enough, but I wanted to know if 12/3 is also fine to use and is just overkill.

Any advice would be greatly appreciated.

Thanks - Joe

I am not an electrician but from my understanding you can use 12/3 and cap off the red wire at both ends. If in the future you need a 240 volts appliance installed you can use this 12/3 wire and use the red. I guess the short answer is YES and cap off the reds. 12 gauge for 20 amps is correct. Remember that you can not tap from the kitchen if the power to new receptacle is to be used outside the kitchen which I do not believe is your case.
