The equations in the 2018 edition of IEEE 1584 are more complex than the 2002 edition. Have you ever performed arc flash calculations manually using either the 2002 or 2018 edition?

Both the 2002 and 2018 calculations in Jim's class. I'm not sure that I have recovered. Quite complex.

Oops. Yes there is quite a bit to it as you found out.
