which limits power to around 1100W All those 1800+ watt hair dryers that are used very commonly in the U.S. are wondering where you got your wattage limit from

  Continuous vs noncontinuous overcurrent rating.[1] Depending how you get your appliance approved, you can draw more. The actual requirement is 3 hours, but like all regulations you have to look at intended usage: [1] https://www.csemag.com/articles/understanding-overcurrent-protection/ https://www.csemag.com/articles/understanding-overcurrent-pr...

    The comment I replied to said the U.S. was limited to around 1100W which is why The U.S. doesn't use tea kettles. I reply with a very commonly used device that uses over 63% more power than 1100W showing that obviously isn't the reason the U.S. doesn't use tea kettles. And you reply with essentially, "Oh, but that's because the hair dryer isn't used continuously for 3 hours". Did you think a tea kettle is used for 3 hours continuously?

      Please actually read what I said: there are differences in the appliance approval process which determines how much continuous power you can draw from an electrical circuit. Why would a manufacturer bother trying to prove discontinuous draw when they can just current limit, use the same element they do everywhere else with the same resistance, and not worry about it?

        I read what you wrote but still fail to see what it has to do with a claim that 1100W is the limit on US circuits and that is the reason Americans don’t use electric kettles. Because that is what was being discussed.
