Re: Information on GFI
Good article, trying to be clear, but unavoidably a bit geeky. A layman's eyes might be glazed over by the middle of the article. That is a shame, because they might stop reading before the author gets to the part about causes of false trips. That section is important for troubleshooting, even if the "engineerical" details of how the devices operate are too much.
One source of false trips not listed that I have experience with, and the author might not, is strong radio signals. Using a walkie-talkie in an RV with GFCIs is a reliable cause of false trips. The AC wiring acts as antennas, and if enough signal is gathered and sent to the circuit board, it reacts and cuts the power the same as it would for sensing a current leak.
