I understand that in wireways and wire troughs, you are permitted to install up to 30 "current carrying conductors" without adjusting ampacity for bundling. The instant you add a 31st wire, the 31-wire derate factor applies.
How does this work when you install a wire trough divider?
Does the full count of wires on both sides matter?
Or just the count of wires per side of the divider?
