Hello,

I am new to electrical and would love to learn. I have a question. Can you place Power, Control signal, Feedback, and Digital all into one conduit? What are pros and cons? if it does have cons, can there be an exception if you add something to allow it?

Thank you,
U.S

The very first answer to that question is that the TS needs to consult the NEC (National Electrical Code), relative to insulation requirements. They are very detailed and quite useful.

In addition, there are a whole lot of recommendations by respected sources that relate specificly to that topic.

Aside from that, as an engineering professional, I would never do that, UNLESS the control signal and feedback signals use fiber optic cables.

thank you for the feed back. it would need to comply with NEC. You stated, it won't be a good idea. can you tell me the reason behind this? is control signal and feedback the most problematic?

This is involve with 24VAC/VDC only
