That confuses me. You can plug a 15 amp plug into a 20 amp receptacle (and circuit) and that is not considered unsafe. Why would plugging in a 20 amp plug (with adapter) into a 30 amp receptacle be unsafe? That is not the same thing as using a 15 amp rated to wire a 400 amp circuit. I ve always heard that the breaker is there to protect up to the receptacle not what is plugged into it.

I guess it just the dang black magic. :-)

What you just asked is a good question, I don’t see a problem running something on a circuit that’s rated higher than need be. My BS (3.6 HP, 30 amp) runs on a 50 A welder circuit all the time. It does have overload protection.) In my mind it goes back to the fact that the circuit breaker’s job is to protect the wiring, not the tool.
