Drip loops, pretty self explanatory.
The drip loop simply provides a place for any water collecting on the conductors a place to drip off instead of following the conductors down to the terminals of the equipment connected to them.
The NEC put the drip loop requirement in the Service Conductor Section simply because those are the wires that the NEC has control of.
The NEC could not tell us to put drip loops in the utility wires as those are under the utility control.
That said as long as there is a drip loop below the weather head or cable sheath the function of the drip loop is guaranteed and the intent of the NEC has been meet.
IMO an inspector who fails the service in the above picture simply because the "U" bend is in the utility conductor and not in the service conductor is someone who has forgotten the intent of the rule.
I will also point out that in this area I leave the service conductors hanging out at the service point, then the electrical inspector looks at the job, approves it and tells the power company
to make the connection.
It is the power company
that forms the drip loop most times, not the electrician.
Maybe I am missing something here, I could change my mind if someone would explain why it makes a difference which side of the splice the drip loop is on.
