NEC Code Changes

This fault current calculator is a quick an easy way to estimate the maximum available fault current at a location in the power system. It will even create a label to meet the requirements of NEC Section 110.24.

This resource is perfect for those who want an indepth knowledge of how to properly select overcurrent protection.  This is a must have for your power systems engineering library..

This is a work in progress.  My goal is to have a resource that provides information regarding history and changes for each section of the NEC.
