lightening cable melted while charging ipad pro

The charging cable that came with our ipad pro melted. The cable cracked open and peeled under normal use. This was a few months back. We peeled that off and were going to put electrical tape, but haven't yet. This morning it melted noticeably and threw a circuit breaker. Maybe it's been melting all along and we haven't noticed. What's going on? This is a huge hazard. Has Apple solved this? What to do? Cables shouldn't melt. Cables shouldn't crack under normal use. It's a $32 cable that should not have cracked and peeled in the first place! This IMHO is a serious flaw in the cable itself. I have seen where others have had this issue with phone chargers, that's why I posted under Ipad. Is this a known issue and is there a solution from Apple. I don't want a new $32 cable that's going to do the same thing!
