Hi,
Could someone remind me where the table is for adding various size conductors? I believe we use sq inches. Was that in conductor properties?

Table 8 in the back just before Appendix A. 2005 book 70-635

I think that is what you want.

Thanks Dennis.
I'm sizing the ground for the secondary of a 300 kva trans. Three 4/0 per phase to three disconnects. I believe I need to add the 4/0 together for the size of the ground. I come up with 2/0cu.

If you are looking for the GEC then yes 2/0 is correct.
