I've starting making a Table of Contents for the Tables and Figures in the 2011 NEC Handbook. I've made it through the first 340 pages, copying down all of the table names and page numbers. Does anyone want to help? We can post the completed list here to share. I can take pages 1-500. Any...

Ok I was confused once again, so hopefully you can learn from my mistakes. On NCEES, Power exam #531: From here, I made the mistake of saying that the impedance angle was -45 and I was trying to use powere triangles to come up with 5000 MVAR. But the impedance angle is 90, so:

I am confused about the solution to #4. 3 phase transformer, 3600kVA, Z = 7.5%, turns ratio=25, Vpri = 11kV. Assume line value is base value. Find Z actual on secondary. The solution says Zbase = V base / (sqrt(3) * I base) I don't think this is true for both wye and delta transformers and...
