Generator Bonding Plug
Finally, a simple solution for a simple problem with your RV portable generator and its power/surge protector.

Some RVs have built-in power/surge protectors or some owners choose to use their pedestal plug-in power/surge protectors even when operating on portable generator or on inverter. In many cases, the power/surge protector device will report an "OPEN GROUND" or “E2” or "OPEN NEUTRAL" fault. The equipment is looking for an earth-ground connection, bonding in a word. This can prevent your RV from ever receiving power.

To resolve this problem, all you need is Micro-Air’s Portable Generator and Inverter Bonding Plug. Truly plug-and-play, all it requires is for you to plug it into the outlet of your generator or inverter and then . . . walk away! It bonds the open ground and permits your power/surge protector to operate. No need for metal staking to ground your generator. This does the job.
