Portable Generator Bonding Plug – Neutral-to-Ground Adapter for EV Chargers, RVs, and Surge Protectors
Ensure your portable generator or battery inverter works seamlessly with modern appliances, EV chargers, surge protectors, and RV electrical management systems using the Portable Generator Bonding Plug. Many portable generators utilize a floating neutral electrical system, which can cause devices to fail, trigger error codes, or prevent proper operation. This plug bonds the neutral and ground within the generator outlet, allowing your equipment to function like a standard household electrical system.
Without a neutral-to-ground bond, sensitive devices—including EV chargers, smart appliances, surge protectors, and RV electrical management systems—may display open ground errors or fail to operate. The Portable Generator Bonding Plug ensures your devices operate safely and reliably, while maintaining proper generator setup.

FAQ
What is the BP15A bonding plug used for?
The BP15A bonding plug is used with compatible portable generators or inverter generators that have a floating neutral. It creates a neutral-to-ground bond at the generator outlet so certain RV surge protectors, EMS units, power monitors, and connected equipment can recognize the generator power correctly.
How is the BP15A different from the BP15B?
The BP15A and BP15B are both neutral-ground bonding plugs for compatible floating-neutral portable generator applications. The BP15A provides the neutral-ground bonding function only. The BP15B includes the neutral-ground bonding function plus built-in surge protection for compatible generator use.
Does the BP15A include surge protection?
No. The BP15A does not include built-in surge protection. It is a neutral-ground bonding plug only. Customers who want a bonding plug with built-in surge protection should consider the BP15B.
Is the BP15A considered whole-house surge protection?
No. The BP15A is not a whole-house surge protector and should not be used in a home outlet, electrical panel, RV pedestal, campground pedestal, or building receptacle. It is designed for compatible portable generator and inverter generator applications where a neutral-ground bonding plug is appropriate.
What problem does a neutral-ground bonding plug help solve?
Some portable generators have a floating neutral, which may cause RV EMS units, surge protectors, or power monitors to show an open ground, open neutral, generator compatibility error, or no-power condition. The BP15A bonding plug helps correct that condition when used with the correct type of generator setup.
Is the BP15A mainly for portable generators?
Yes. The BP15A is intended for compatible portable generators and inverter generators with a floating neutral. It should be used only where a neutral-to-ground bond is appropriate for the generator application.
Can the BP15A be used with an RV?
Yes. The BP15A can be used with a compatible floating-neutral generator when powering an RV, especially when the RV surge protector or EMS requires a neutral-ground bond to operate properly.
Does the BP15A provide power to my RV or equipment?
No. The BP15A does not supply power by itself. It plugs into an unused compatible generator outlet to create the neutral-to-ground bond needed by some RV EMS units, surge protectors, or power monitoring devices.
Does the BP15A replace a surge protector or EMS?
No. The BP15A does not replace an RV EMS, surge protector, circuit breaker, fuse, transfer switch, or other required electrical protection device. It only provides the neutral-ground bonding function for compatible floating-neutral generator applications.
When should I use the BP15A?
Use the BP15A only when you are using a compatible floating-neutral portable generator or inverter generator and a neutral-ground bond is required for the connected equipment, RV EMS, surge protector, or power monitor to function correctly.
When should I not use the BP15A?
Do not use the BP15A in a home outlet, RV pedestal, campground pedestal, building receptacle, or any outlet that is not part of the intended compatible generator setup. It should not be used to correct improper wiring or create a bootleg ground.
Can the BP15A be used on a bonded-neutral generator?
The BP15A is intended for floating-neutral generator applications. If the generator already has a bonded neutral, using an additional bonding plug may not be appropriate. Always verify the generator configuration and consult the generator manual or a qualified electrician when unsure.
Can the BP15A be used when connecting a generator to a home transfer switch?
Use caution. Many home transfer switch and electrical panel setups already have a neutral-ground bond at the main service equipment. In those cases, the generator may need to remain floating neutral. Consult the transfer switch instructions, generator manual, and a qualified electrician before using a bonding plug with a home backup power setup.
Does the BP15A eliminate the need to ground the generator?
No. Bonding and grounding are different electrical concepts. The BP15A creates a neutral-to-ground bond at a compatible generator outlet, but it does not replace any grounding requirements that may apply to the generator, equipment, or installation.
How do I know if my generator has a floating neutral?
Check the generator manual or contact the generator manufacturer. A qualified electrician can also test whether the generator has a floating neutral or bonded neutral before use.
Is the BP15A plug and play?
Yes. The BP15A is designed to plug into a compatible unused generator outlet. No tools, rewiring, or permanent generator modification are normally required.
Can the BP15A be used indoors?
The BP15A should be used only with a generator being operated safely according to the generator manufacturer’s instructions. Portable generators should never be operated indoors, in garages, or in enclosed spaces because of carbon monoxide and electrical hazards.
Can the BP15A be used outdoors?
The BP15A should only be used in a suitable protected generator outlet and should not be submerged, exposed to standing water, or used in a way that allows water to enter the electrical connection.
Can the BP15A be used on 240V outlets?
No. The BP15A should only be used with the correct compatible outlet type and voltage rating for the product. Do not use it on incompatible outlets or electrical systems.
Can I use more than one bonding plug at the same time?
No. Use only one neutral-ground bonding point in the generator setup. Multiple neutral-ground bonds can create unsafe electrical conditions and should be avoided.
Who should use this product?
The BP15A is intended for users who understand their portable generator setup, RV power system, EMS unit, surge protector, or power monitoring equipment. When in doubt, consult a qualified electrician, RV technician, or generator technician.
Does the BP15A include a warranty?
