NEC 725.136 (H)

What does this section allow? It sounds to me like I can run class II wire in the same raceway as power if it is installed using class I wiring methods. Does that mean so long as my conductor is insulated to the proper voltage I can run class II in the same raceway with power? Hoe did I miss this change!

It's not a new change.
You can from my understanding of it run class 1 and class 2 in the same raceway. But I also think you have to mark all class 2 sources as class one???
I never told our guys about it. We send stuff all over and it's subject to a lot of inspections so we don't push our luck by getting gigged by someone who we will never be able to make them see it's legal.

If the power supply is Class 2 Only then you cannot install the wiring as Class 1.
