An RCD measures the difference in current flow between the phase and neutral, so it will trip in this scenario. An alternative path to earth is precisely what they're designed to detect.

    Ah yeah, you're right, my mistake. It's wild to me as an Aussie that they aren't universal in the States. Plenty of houses (or outlets?) don't have them IIRC?

    Plenty of old houses still don't have them in Australia and NZ, but they're required on power circuits in new builds.

    As they should be, they're an incredible technology.
