That raises an important question for myself, after looking through John's articles, I realize that the way I hooked up our generator did not isolate it completely from the street. The neutral leg was still continous to the street. To really isolate the generator, I should have disconnected the neutral leg at the panel.
I did make sure no hot leg could possibly feed back by putting that lock on, main breaker off, but now I'm wondering about the neutral. The neutral is also grounded to the physical ground at the main box, so if I disconnected the neutral leg at the panel, I might have lost ground! Gotta take a closer look, and next time take off for Maine....
EDIT: I just checked the whole situation, the panel is grounded separately out to the neutral, and from there to the ground stake.
