Extra low voltage and low voltage are mixed in every machine I have seen which uses them. There are areas which Extra low voltage is probably mandatory such as pool lights. Low and high voltage are never mixed. 480V is considered low voltage by most supply authorities, 11Kv is considered high voltage. I'm thinking 725.136 specifically says that one should separate by barrier, or distance from power circuits. Infinity discussed this is post 4. The separation specifics are in 725.136.A - I.
