This situation has 3 parallel 3/0 15kV MC cables feeding a productin facility. One of the three cables is very hot to the touch (I couldn't keep my hand on it for more than 10 sec.) while the other two are not even warm. I'm not sure of the age but probably 30+ years.
My first thoughts are bad terminations, but 2 0f 3 conductors of one phase would have to be bad to cause only one cable to get hot. that seems unlikely.
Does anyone know of any other cause for a cable to be hot the entire length. If ther were insulation issues would that cause the cable to get hot?
Any help would be much appreciated.
