This is an interesting change. I was taught to think that ONE reason for all the efforts to separate class 2 and 3 wiring from class 1 and power wiring was to protect the technician who thinks he is only dealing with 24 volts from inadvertently getting nailed with higher voltages. I guess this change pretty much nullifies that notion. All they must be concerned with is fire, induction, and fire/smoke characteristics of unprotected cabling!
