I am hobbyist and I am trying to build Wi-Fi power outlet. Right now it is personal project but I want to bring it to a mass production if I will succeed. I have never built such things before and I am curious about rules and regulations regarding such devices. I want to ensure that I won't make anything bad, stupid or hurt someone.
For example, I know that in Russia maximum power rating for such devices is 1kW. Is there something like this in the US?
I want to ensure that my device is safe and complaint with common regulations.
