I am a little confused over the difference between service and tap. We have a couple of small equipment shelters and I need to power them. Panel for each shelter is located inside, near the point of entrance (230.70(A)(1)). Does this mean I can treat the conductors as service drop and not tap? The reason I am asking is that I want to know if I have to protect the conductors because transformer is more that 25' away from the shelters.
Any advice will be appreciated.
