When running multiple circuits through a conduit, how do you identify each and keep them with their respective neutrals? Do you normally use different color for separate ungrounded conductors? Use tagging tape? Just wondering if there's a common or required practice to keeping track of your circuits from junction to junction. Aside from a few cafes I've never done commercial electrical work. I like to keep all circuits well identified and labeled throughout system but still trying to find an accepted and uniform way to do this.
