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.

well, he wasn't very specific so I tossed out one of the more common sizes I use.

Might be useful in the future, instead of asking what appears to be a question with no answer

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

Like I said, most charts like this are incorrect or even useless.
