I'm certainly not an electrician but maybe someone who is can help me with this. I recently bought a new generator for home backup, camping, and remote powering of tools. The generator had a bonded neutral (the neutral is connected to the ground circuit). The neutral needs to be "floating" when connected to my home for back-up power but should be "bonded" when used as a remote power supply. My question is... Why would you want the neutral connected to the ground for any application? I always thought that the current ran (normally) through the hot (black) wire to the load then returned via the white (neutral) wire and that the ground was just and alternate path to get rid of the voltage in case of a short. Wouldn't connecting the neutral to the ground create current in the ground circuit? Apparently that isn't the case as the neutral and ground are tied together at the main box in a home electrical system. And finally why would two bondings in one circuit create a problem? It seems like if bonding the neutral to the ground in the home is a good thing that bonding the neutral to ground in the generator or anywhere else would be good as well. As I said, I'm not an electrician but I have done many electrical hobbies and have done many home circuits (mostly lighting and outlets) and I do know the right way to make the connections but I don't understand the why and am hoping someone can make sense of it for me. I've spent over 7 hours researching this online and the only responses that I've been able to find are "Because that's the way the code says to do it." OK, I get that but being able to understand why makes it a lot easier to remember.
