Can the Positive DC and Negative DC Cable Get Routed in the Same Conduit?
My experience with this is that yes, Dc positive and negative cable can be routed in the same conduit. You do not however want to run AC and DC together at any time in the same conduit. You will be okay to do this in the same conduit.
