Hi All,
I'm curious as to the correct answer to this. Do Modern GFCI's not work is the line/load is reversed? I have been told that if they are reversed than the "Test" button on the GFCI will not work properly. Is this true?

I would think that was true, because the test button would create "slight" connection to ground simulating a fault, but if the circuit is reversed, that would just connect the neutral to the ground and they are both at the same potential already.
