Standards as High as Your Own

Greetings CQD,

Thanks for your daily responses. It is truly understood that you can’t read more into the questions than what is at face value. Here is a general question about the NEC Scope. Does the NEC apply to the service drop connected to the Weatherhead conductors of an overhead riser? 

Bernie Reynolds



Hello Bernie,

Those comments are very appreciated. As for your question, the NEC has rules that apply to the service drop-in regards to height and point of attachment as indicated in Section 230.26 for the point of attachment, and 230.24(B) for clearances above grade, and others. The term service drop, by definition, applies to the overhead conductors between the serving utility and the service point. The service point in these situations is often the point of connection between the overhead service conductors and the riser conductors that emerge from the Weatherhead. So the response to the question is yes, but it depends on the location of the service point. The NEC typically applies on the load side of the service point and the NESC applies on the line side of the service point. The terms service point, overhead service conductors, and service drop are all defined in Article 100.
