Just finished fishing some 4 awg wire through 1 inch conduit. There are numerous twists and turns in a small area. Very difficult getting it through, but with time and patience and improving technique got it through.
My question is the scuffing that happened. I included a photo. It seems superficial but in my OCD decided to cover these with electrical tape.
This will be handling the solar input. Any concerns?
