Hi guys,

Thanks so much for all the replies on my first thread. I decided to refresh this thread with a new question.

Based on your comments, I decided to run 20A dedicated branch circuits to my studio. Keeping computer/peripherals on one circuit and my outboard audio gear on another one. I also decided to run isolated ground circuits.

Question:

Would I benefit from using 10/3 wire over 12/3?

It seems like a heavier gauge wire would result in more consistent supply and lower impedance (but I really don't know why . . . that's why I'm asking you guys!)

The next problem is that if 10/3 would be beneficial, where can I find a 20A breaker that will accept the bigger wire. The Cuttler breakers I saw at HD today were for 14 or 12 gauge.

Any thoughts?

Thanks again,
Mike
