• Conduit Fill: Chapter 9 Note 7 round-up for same-size wires, so 22 #14 THHN in 3/4" EMT now reads OK, as in Annex C.<br>• Box Fill: each device yoke is sized by the largest wire on that device (314.16(B)(4)); studs and hickeys count once per type; each EGC past four adds ¼ (314.16(B)(5)). The old version could under-count a box with 5+ grounds.<br>• Wire Size: 240.4(D) small-conductor limit
