Right here.
Service entrance weatherhead clearance from a door into a hay mow? It's not a window, and it's not a deck or balcony. Just a door into the sky. I haven't really opened the book yet, but my gut tells me this might be a grey area.

No. I really don't know much code. I just the about the things that seem to crop up on a regular basis, and the about the things I do a lot of. I haven't looked this one up yet, but I thought it was sufficiently unusual to post it here for discussion's sake.

My guess would be a faded yellow, given that we are working with hay. ;) (Sorry about that. :roll: )

This is outside my area, as I don't get involved with services other than underground feeds to transformer vaults, and the like. But 230.9(A) might have the answer you need. Service conductors must be at least three feet from "windows . . . doors . . . and similar locations."

So people don't use this door but equipment puts hay in or out?

Um.. yeah, more or less. A hay elevator (like a conveyor) is wheeled in place, and a man stands inside the doorway to take the bales off and stack them up.

Well you can't be beneath it.

Since you don't feel like looking it up....:smile:

Let me assure you that it would not be a gray (yellow? :wink: ) area for us. The service linemen have to be able to put a ladder to the point of connection of the service drop to the building and putting it up against a door would not get it. Additionally, we have a maximum of 22 feet to the point of termination so the ladder will reach. Not all of our trucks have buckets and a ladder must reach all weatherheads. OK, not an NESC or NEC rule but a requirement by at least one electric utility that must be met to receive power. :)
