I have an issue. About a year ago I started thinking about dropping a new sub-panel in my basement shop. I bought the panel and on eBay I found a lot of 25 amp breakers, not realizing that I was creating an issue for myself at the time. So I guess I am now between wire gauges Ie. 20amp breakers protect 12awg wire. My largest loads are the 3hp machines (Unisaw, planer, bandsaw). I would like to run the 12awg wire if possible just because it is easier to work with. My question: is it against code to run 12awg via 25amp breaker for non continuous duty electric motors? I've seem some mention that there are special tables in the NEC but I don't have access to a book. Or, should I be running 10awg regardless? Or should I put the 25amp breakers back on eBay and buy 20 amp breakers?
