This neutral ground connection plug is suitable for portable generators that come with recreational vehicles and campers, and can be matched with 15A sockets on generator control panels of brands such as EcoFlow, Honda, and Champion. Portable generators with floating neutral wires or surge protectors may not be able to supply power to RVS due to the detection of open ground faults. This plug can provide the necessary grounding conditions by connecting the generator's neutral wire to the ground wire, solving the power supply problem. No complex operations are required when in use. Just insert the plug into the corresponding socket of the generator, and a correctly connected power supply will be created. Before use, please refer to the generator's user manual to confirm whether it is designed with a floating neutral point. Material: Resin.
