I'm doing a basement remodel and I just uncovered a spot where the previous owner ran individual no 6 awg cables for the feed to an electric range. There are 3 black no 6 awg cables and a green one. The cables are run through holes in the floor joists... about a 50 foot run. Is there any real issue with that? I'm used to seeing the 3-1 individual wires wrapped into one cable, not run individually. Is it a big deal? I could probably put it in conduit, but it would be a real pain in the ...
