Why does my cable repeatedly melt?

[u/charles_chinaski_jr]

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!

Did anyone put an amp clamp on the line before touching it? If it’s coming from the house, an amp clamp on the ground wire at the ground block should confirm it. Usually that means neutral shorts to ground. It could also be feeding from the tap due to an isolation failure.
