What is the proper way to weatherproof direct burial service entrance conductors coming through foundation underground with pvc sleeve?
I have seen people fill pvc sleeve with window foam. I have also seen it done with tar. I had also seen people use nothing.
What any of the first two methods be ok by themselves?
Will tar eventually break down the insulation on the wires?
What about weatherproofing on outside of the pvc sleeve, what would you use?
