I am 'gasp' teaching a 2nd year apprenticeship. We came across a Mike Holt question in a test that I couldn't figure out. Recently Al Hildenbrand posted the graphic that relates to this question. It was in August, but for some reason the thread is closed. It has to do with the toroid coil. The question was a true false and stated (without quoted because I don't have it in front of me. A neutral to case connection on a device downstream of GFCI device will not allow the GFCI to be reset whether there is a load on the device or not. The answer is true. I don't see how. I have a couple of issues, first it is picky, but why use the word "case" when I believe the meaning is bonded to ground. The case could imply the plastic, which I honestly first envisioned when reading the question. When I determined he meant ground, I still wonder how the device is prevented from resetting. Unless there is current flow inside or outside the torroid. If there is current flow then technically there is a load, right? Whether and intentional load or not, it is either loaded or a direct short in order for current to flow. It would be great if that graphic I am referring to could be posted again. The thread was entitled, "testing GFCI receptacles."
