This is a question I had on a tap rule quiz I gave my apprenticeship students: "You have an outside feeder tap running between two buildings. The tap conductors are copper tri-plex cable attached to a chain link fence at a height of 7'. Legal or illegal and code ref". We all know it's illegal, that's not the issue. The issue was the section. Specifically: 240.21B51 makes it illegal because they are not "suitably protected from physical damage" Two of the students sited 230.50B and said this would apply even without the tap rule. I don't know if 230.50B would apply to a tap or is it for a (protected) feeder or what. So ... what do you think: would 230.50B make this illegal?
