20 Amp Dedicated line: 10 gauge vs 12 gauge wire


Is there any issue running a 10 gauge wire in a 20 amp dedicated line vs. a 12 gauge wire.
It seems that a 10 gauge wire would heat up less.
Thoughts/comments?
Thanks.

No problem using 10 gauge instead of 12, however if all your outlets are rated at no more than 20amps, you should use a 20amp breaker.
