Designed for floating neutral generators - Creates a neutral-to-ground bond for portable generators that require an external bond so connected protection devices and testers can work properly Built-in LED status indicator - Green LED provides quick visual confirmation that voltage is present and the bonding plug is operating as intended Integrated surge protection - Includes built-in ITMOV surge protection to help reduce the impact of voltage spikes on equipment connected to the generator Simple plug-in setup - Plugs into a standard 15A 120V generator receptacle with no wiring required for fast setup, testing, and troubleshooting Use only when your generator requires it - Check your generator manual before use because some inverter generators already include an internal neutral-ground bond and do not need a bonding plug Neutral Ground Bonding Plug for Portable Generators This bonding plug is designed for portable generators with a floating neutral that require an external neutral-to-ground bond. It plugs into a 15A 120V receptacle and helps create the proper bonding condition needed by many EMS units, surge protection devices, and outlet testers. A built-in green LED indicator gives quick visual confirmation that voltage is present and the plug is functioning. Integrated surge protection adds another layer of protection for connected equipment during generator use. This bonding plug is intended only for generators that require an external neutral-ground bond. Always check your generator manual before use. Some inverter generators already include an internal bond and may not need this device. Never use it with a home electrical system.
