On April 26th 2022, IEEE (PI)2  hosted a technical presentation by Charles Goertz on “The Short Circuit Current Rating” 

The presentation covered the definition and purpose of the SCCR in protecting personnel and equipment. Charles discussed methods of determining the SCCR and how the National Electric Code (NEC) uses the SCCR, as well as pitfalls to avoid and how the available fault current is used with the SCCR. Charles also presented several case studies and problems he has seen as an on-site compliance engineer – including mislabeled equipment and unintended wiring errors. While you can calculate the SSCR by hand, there exist free spreadsheets where the proper data can be entered that will streamline the process. The challenge is how to make sure you have the correct information. One-line diagrams and field verification of the wiring is required, and field verification can be challenging if wiring diagrams have not been updated to “as-built”. Charles’ humor and case examples kept the presentation lively and interesting.
