  • Not for 4 awg ground wire
Item Package Quantity: 1 Size: 1 Port
I had contacted the televes technical support regarding grounding and they advised 4 awg, unfortunately this doesn’t fit with the ground wire. I will keep this until I can get one that will fit Other than that, I don’t know if it will work with lightning. Something to hope stays away LOL
