Most portable generators have a floating neutral. The Surge Guard electrical protection units will see this as an open ground condition and not allow power to pass through. To solve this problem you simply plug this bonding plug into a 15A receptacle on the generator control panel. This will create a neutral-to-ground bond and the open ground issue will be resolved. Please check the owner's manual of the generator to make sure it was designed with a floating neutral.
Not necessarily. If you are connected to a generator, your Surge Guard may display the “OPEN GROUND” fault. This is because your generator has a floating neutral, which the Surge Guard sees as an open neutral. To correct this, all you need is the Generator Bonding Plug. Simply plug it into one of the outlets on your generator and the issue should resolve itself.
