I had a tech come out last week to upgrade to the power and he added another pair to make it work. I went out there to make sure he tighten the copper lines to the nuts well. I tried to tighten the nuts but they were super tight already. is bad to have it super tight where the copper is pinched and flat behind the nuts? or should they redo it and not make it so tight. I have over 20000 CRC errors daily and a few fast disconnects.
