Sorry I meant the point of connection. It seems to be an issue on a lot of current jobs. The structural people do not really care much about NFPA 13 and its requirements they seem more interested in actual weight applied. On a current project the notes call for a brace if the hanger is not within 3" of the panel point and there is a note about a maximum 200 pound load even with the brace or at the panel point. They are not convinced the 250 pounds of addition safety applies to their design. It seems silly but how do I get my system compliant without trapeze hangers to split the load. I bet the review of the seismic will be even more fun. Dave Canham

The point of attachment is just the weight if the pipe plus 250 (could say 1 times the weight of the pipe). As for the 250 no longer being needed with OSHA requirements, we tried a proposal deleting it and the TC beat us about the head and shoulders. It is here to stay.
