You'll have to be more specific. There is NO one answer to this question.

DO NOT trust those crappy charts in Home Depot. They are often wrong.

Roughly speaking, 15A=14ga; 20A=12ga; 30A=10ga, etc, more that that needs a code book.

If you were to cut off enough strands you could surely attach it to a 15 amp breaker.
