lol. are you going for EE, I thought about it, for 2 seconds, then I remembered as much as I like that stuff, I dont want to spend my life doing it. and I think hat the whole 15a, 20a thing differs on region and on wiring codes. In oklahoma, I am pretty sure that we have to have a 20amp socket to have a 20 amps breaker, otherwise, if we are using the plain jane wall socket, then we can only have a 15amp breaker at the breaker box. That may just be a code of the city I live in, I'm not sure.
