What service drop means
The service drop is the overhead wiring from the utility pole to the house.
Where it matters on a electrical job
The drop belongs to the utility, but the mast and attachment point on the house are often the contractor's work. Clearance from windows, decks and roofs matters, so check it on any job that adds a deck or porch near the drop.
What the model code says
- The code defines the service drop as the overhead conductors between the utility and the service point. (IRC 2021, Chapter 35)
- Open overhead conductors need at least 3 feet of clearance from the sides of doors, porches, decks, stairs and windows that open. (IRC 2021, Chapter 36)
Check which code edition your building department enforces for service drop before you quote.
