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.

Even with the same length for all runs, the voltage drops will be different for each circuit. This is because power amp draws more current and it would see a slightly lower voltage.
