I'm trying to design a pull box and I am having difficulty interpreting NEC 314.71 for the sizing requirements. I have a straight pull through the junction box and it states that the length of the box needs to be 48 times the outside diameter, over sheath, of the largest shielded conductor or...
Thanks everyone for the feedbacks and recommendations. I just think that the SKM library is not adequate compared to ETAP. Another issue I found that is its limited fuse rating in the library (I could not found the right size I wanted).

I am new to coordination studies, wondering are there any good resources out there peopel can recommend? I have just started using SKM for the studies, and I feel like the library is very limited, am I missing something? Are there any good tutorial out there for it?
