@cleeds I guess the electrician who willingly installed that line in that outlet was violating code? The building inspector too? HmmmCodes vary by location; the NEC establishes only the minimum guidelines. If your inspector approved the install and you're comfortable with that, that's fine. If you don't see the possible hazard of putting a device rated at only 20A on a line capable of delivering 30A through it, then there's nothing further I can add. It's surely a risk I wouldn't and didn't take. Instead, I built several 30A lines, but used a 20A breaker on each. That's a common and perfectly acceptable practice.
