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.

Neither wire will heat up noticably, because you will only draw a couple of amps no matter what the wire, outlets, and breaker are rated for.
