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?

I think they have you. If the feeder supplies the other building then it is covered by 230.50 B. I guess you've got a sharp group of apprentices. Alan
If it was easy, anyone could do it.
