I've been doing some reading on short circuit calculations and came accross a book that mentions upsizing the ground conductor (250.122) for the available fault current. I've ran lots of short circuit calcs and have yet to look at upsizing the grounding conductor, nor has the size of the GEC been brought up during plan review. I'm not saying this is right, but I have to wonder how many people are upsizing the GEC during design for the available fault current?
