Wasn't there something that previous versions of the NEC allowed either yellow or orange for external sources but the latest version restricted it down to just orange? I thought I saw something about that on here a few months ago.
Thank you so much guys. In our panels here in our facility I have seen yellow and orange but from now on since the latest changes to the code, I will use "Orange" moving forward.
Here's a question.
We normally have a cabinet that houses AC and with that the power supplies. The DC power then goes to other cabinets/junction boxes to serve them. This is always blue/wht-blu.
Do you think that the wiring outside of the AC box would need to be orange?
