I have TJI joisted intalled that I need to run some electrical wires through.
Question 1# The knockouts in parallel joists don't line up. Will wires that zigzag slightly, instead of being straight, pass code?
Question 2# How many wires can I run through the knockouts and along the same paths? Such as, can 3 12-2s go through the same series of knockouts?
