Okay, I came across a 4.5KW residential water heater the other day (50 gallon unit). It was fed by a 2P20A breaker. Has worked flawless for several years. First one I have ever seen. My knee jerk reaction was to say it needed to be fed with #10AWG on a 2P30A. However, I was informed that it is NOT a continuous load and therefore is okay at a draw of 18.75 amps. Is this correct???
