Hey Dextor007. I Did check the wires, 14-2 600v rated to carry no more than 15 amps. Gofish104 was right about the wiring not being able to support more than what the original breaker is rated for. My thought process for wanting to add a larger breaker on the same line was that I wasn't ever going to run more than the 13 amps so I just didn't want the breaker to break. But now with more careful thinking, I'm just going to use the two circuits instead of one.
