Power and utility
Service drop
A service drop is the set of overhead wires that run from the utility's last pole to a building.
OSHA defines a service drop as the overhead service conductors from the last pole or other aerial support to the splices that connect to the service-entrance conductors at the building. Oncor's guidelines set clearances for drops over roofs, driveways and pools. The drop ends at a weatherhead or a service mast.
Homes with buried power have a service lateral instead. If a service drop is down, sagging or touching a tree, stay far away and call 911 and the utility. Never touch it. See emergency electrical help.
