For electrical users, a somewhat common inquiry is how to document multi-section panels. Please watch the video below for a method that lets you utilize circuit numbers over 42, and clearly document that the panel represents a multi-section installation.
Please provide any comments to let your fellow users know if this method is suitable... and if not, cite any applicable regulatory requirements that make such a method invalid.
Did you know? The Static Pressure reported in a Duct System Schedule reports the same value that the System Inspector reports as the Static Pressure at the duct section closest to the inlet to that system. This value is the sum of all the losses along the critical path for that system, including losses in duct segments, fittings, air terminals, and other accessories.
The Pressure Loss value you see in the inspector is the sum of the losses only in that section (which generally includes ducts and fittings of the same flow and size).
Recently, one of my colleagues inquired about how one might create a family with the above capabilities within a Electrical Fixture family. After a bit of tinkering, I believe I was able to achieve the desired behavior for the family. Watch the video to learn how yourself!
