I'm studying for an exam out of the Tom Henry's 2023 calculations test prep book. For Box fill per Table314.16(B)(1) and 314.16(B)5)Seems their answer to this problem is wrong to me as they forgot to add in the single allowance for the first four EGC, they have the portion of the overall calculation for EGC to be 3.375, should be 5.625, Right? final answer 41.875 cu.in.

Where did you come up with the # of EGs? Stated in the problem?

I hadn't updated my spreadsheet for box fill. It is now.

I come up with 39.625 plus an additional 2.25 for the cable clamp = 41.875

So this is in the back of the book in the answers section, the number of EGC is provided in the question which is 10 #12. I just had to run through as many of my resources as I can to make sure I wasn't missing something or there is somehow another way to interpret the code. Thanks for taking the time to look at this!

It is not uncommon to find errors in a book. Hopefully there aren't many but there always seems to be one or two. Good job being ontop of it.
