Class 1, 2, & 3 wiring separation

[cppoly]

Here's what I know:

Class 1 wiring needs to be separated from class 2 & class 3.

Class 2 & 3 can be run together.

I read an article in CSE that class 2 audio wiring cannot be run in the same conduit as other class 2 circuits. Is this correct?

Is this all the separation requirements that I listed?

Take a look at Article 725
