Because I have blocked most of the outlets in my studio with bookcases, I have installed (not sure what they're called) multi-outlet strips with circuit breakers that I plug everything into. At DH's suggestion, the iron is on one all by itself. He said it was not a good idea to plug the machine (which cost more than my first NEW car,) into the same outlets as the iron.
When I am done in the studio, I just have to turn off the two circuit breakers on the bars and everything but the overhead light is shut down. I am very happy with this solution.
