Hi, I have a portable outdoor appliance (pressure washer)that has a GFCI male plug affixed to it. It's 20amps 120v. I was going to install a receptacle outside for it but it got me thinking. If I was installing a receptacle outside I would install a GFCI receptacle ( I have to). But I always thought that you can't put a gfci on a gfci. I don't want to cut the gfci plug and replace it with a regular one. I like to keep things the way the manufacturer does. If I plug the pressure washer into it wouldn't it just trip the receptacle? Am I wrong? Any suggestions.
