Thank-you! I learned something new today! I think I actually used to know this....but had since forgotten! So, has this always been the case for equipment terminals? I know I was taught to always use the 75° column in Table 310.15(B)(16) when selecting conductor sizes on the Block exam when I got my license. (And its always what I use to size wire for jobs) Just wondering if there is any old equipment out there larger than 100A RLA that has 60° terminals.?
