Peter, Most of us knew what dmattox meant with the 25" length of conduit. In fact, I thought it was very clever and would be a neat trick question in a code quiz. And in some cities around me one inch does make a difference between a nipple and a run of conduit as silly as it seems. On a lighting canopy in a store the local inspector made us run another 20 amp circuit to the canopy because one of the lighting circuits listed 16.5 amps. Wouldn't think .5 amps would be such a deal either, especially on a lighting canopy that will continuosly be changed as fixtures are sold.
