    Weatherhead height

    To be in compliance with the 2005 NEC, how high does the weatherhead need to be above the roof-line of a residental home?:-?

    but, if it is, there is no "quick" answer. You really need to look at 230.24 as there are a number of varibles which make the correct answer anywhere from 18" to 8 ft.
    At my age, I'm accustomed to restaurants asking me to pay in advance, but now my bank has started sending me their calendar one month at a time.

    the weatherhead should be at or above the point of attachment, and since the minimum clearance for overhead conductors is 10 ft., the answer, I believe, is 10 ft. (230.26 somewhat confirms this)

    Is the weatherhead height based on height above grade?

    you need enough height on your service mast to get proper clearance for the service laterals.

    I would think, normally, yes, that would be the reference.
    but, obviously, not necessarily so. I picture a weather head on top of a riser on a penthouse built on top of a 4 story parking garage :-)
    now 60 ft above grade. :-)

    also, allow for drop conductor sag. The low point should comply with 230.24(B).
