Electric feed height

Refresh my memory, what is the standard for the minimum distance of an overhead feed line above a deck?

10 feet.

This may be helpful:
(Deck would be walkway/sidewalk)

The cable is about 9 feet off the deck + or-, but is is not directly underneath the deck. Off the the side, but its close. Recommendations?

If it’s within 3 feet of the deck horizontally, it is required to be at least 10 feet above the surface. So, raise the drop or move it beyond the three feet.

Are you asking for a reference according to the NEC? If this is a service drop and the drop is owned by the utility the NEC required distances may not apply.

What I find often, in situations similar to Mike’s, is the deck was built After the service drop had been installed/approved by the local utility company.
