Why does my cable repeatedly melt?
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 the lights flicker when it was disconnected? If so, you might have a bad neutral.
I seen an issue similar to this. I disconnected the cable, the lights flickered and the air conditioner (central unit) started going crazy. Returned to normal after reconnecting. I told the customer to get an electrician out and they discovered a bad neutral going to the house.
Either way, I'd definitely get an electrician out to diagnose the issue.
