IEC v/s IEEE/ANSI - Short Circuit Current Calculation Designations

First many thanks for your posts they are very knowledgeable.

I have question in regards to the Short Circuit Current (SCC) Calculations IEC, IEEE/ANSI.

Basically I am looking for a table (or a comparison table) which shows the detail description, IEC designation and IEEE/ANSI designation for the Short Circuit Calculation, and Just want to know where I can locate it on the internet, supplier manual, books, standards, etc.

I want to get this as I have referred to many articles related to the SCC calculations and now I have got confused which convention is to follow, as they are all mixed up.

I could have referred to the books but then once again same thing would have happened. I could have asked a technical question but I believe if I can get above mystery sorted then I may not need to.

Your help will truly be appreciated.

Kind Regards
