If you want to reclassify class 2 or 3 circuits, to class 1, (14THHN) in order to install in the same raceway with power conductors, would you have to install overcurrent protection as called for in 725.23?

The note in the handbook sure makes it sound that way.
"Revised in the 2002 Code, 725.52 now clearly permits the following two distinct wiring methods for circuits connected to Class 2 or Class 3 power sources
• Class 1 wiring methods
• Class 2 and Class 3 wiring methods
Where it is necessary to locate Class 2 or Class 3 circuits inside the same cable or raceway as a Class 1 circuit, 725.52(A), Exception No. 2, permits a Class 2 or Class 3 circuit to be reclassified and installed as Class 1, providing that the Class 2 or Class 3 marking is removed, that overcurrent protection is provided in accordance with 725.23, and that the reclassified circuit maintains separation from other Class 2 and Class 3 circuits in accordance with 725.55.
