Buying Guide: How to Choose the Right Neutral Ground Bonding Plug
- Should you get a single pack or a 2-pack? If you have multiple generator outlets, a 2-pack offers redundancy and convenience.
- Is your generator floating-neutral? These plugs are specifically designed for generators with floating neutrals and RV power systems.
- Do you need a visual status indicator? Some models include a green LED to confirm bonding is active.
- Compatibility matters: Ensure the plug matches your outlet type (NEMA 5-15P, 120V, 15A) and is suitable for your inverter or conventional generator.
- Safety and materials: Look for durable construction and flame-retardant materials, especially for outdoor use.
Frequently Asked Questions
- What is a neutral ground bonding plug? It creates a proper neutral-to-ground bond on generators with floating neutrals to satisfy RV EMS and surge protector requirements.
- When should I use one? Use when your generator shows open-ground warnings or when your RV’s surge protector requires a bonded neutral.
- Will it work with all generators? It’s designed for 120V, 15A outlets and floating neutral configurations common in portable/inverter generators.
- Is installation difficult? Most plugs are plug-and-play; no tooling or wiring is required.
- Are there safety concerns? Follow basic electrical safety—do not use with damaged outlets, and unplug before inspecting connections.
- Can I use more than one bonding plug at once? Yes, but ensure each outlet requiring bonding is properly configured to avoid redundant bonding.
