Jan 8. I will be taking a state calculation test. It will be a 2 hour test. I assume it will be calculating feeder loads for various type buildings. I could use some advice on the methodology or process of figuring the total load for a given structure. I do know how to use the NEC and do calcs.though slowly. However I have this gut feeling that someone out there has developed a way to do it quick and efficiently and I'd love to find out.
