One-Line Diagram Service Entrance Head/Weatherhead

[leboot]

Hi all, this is my first time posting.

I'm an engineer working on a small project which has a service entrance head (weatherhead). Our firm normally works on larger commercial projects that do not have overhead services. I've made the one-line diagram and noted that the contractor has to provide the weatherhead, but I have a reviewer who is insisting that I use the industry standard symbol for the service entrance head on my one-line (which the reviewer notes as being a triangle with small lines).

Does anyone know what this symbol looks like? All my co-workers are at a loss and I've had no luck with google. I did find a symbol in the national cad standards, but it is not a triangle.

Thanks for any help!

Upside-down equilateral triangle (think upside down delta symbol) with riser one-line going down from right-side vertex. Don't know anything about the small lines.

Don't have my ANSI/NECA standard symbols so can't confirm.

I've also seen a weatherhead symbol that looks like a crowning arc subtended by a chord at say 10 o'clock position...
