Here's an article I just published on NoShockZone about why some generators will trip your RV's voltage protection device. This problem is caused by the fact that most portable inverter generators have a floating neutral bus which isn't bonded to the generator's frame ground. In this article I detail why it can be an issue, and show you a simple way to build a "bonding plug" for a few dollars which will allow you to properly bond your generator's neutral and ground bus together.
