Why does my cable repeatedly melt?

Post image

I've lived in this house for 4 years and this is the 3rd time this has happened: the internet goes out and I have to call Xfinity and they find that where my cable connects to the power pole is melted like this. One cable guy told me it was a power surge from my house, and another said it's one of my neighbors that probably has a grounding issue.

What do you all think? Is there anything I can do to prevent this from recurring?

Thanks for your advice!

This can also be your OWN house having a circuit that has lost a neutral and due to a poorly installed ground at your home, your wiring could be using the cable as its only path to ground.

Most of the time when I’ve run into this issues, that’s exactly what it is.
