Do all the
calculations that apply, then add them up for the total space needed [314.16(B)].
If it's not
less than twice the minimum length required for free conductors in 300.14, count
it twice. If it's shorter than that, then you count it once if any part of it
leaves the box. If it qualifies as "a conductor, no part of which leaves the
box" and meets the length requirements, then you don't count it at all--but such
conductors are not the ones addressed by 300.14
count as a single volume allowance per Table 314.16(B), if inside the box [[314.16(B)(2)
A single volume allowance [314.16(B)(5)].
