Adam, My Canadian Electrical Code requires "separation" between conductors of different "systems". I believe the NEC is the same/similar. You may notice a flimsy (yet stiff) paper(?) barrier between the AC and DC wiring areas in some AC/DC inverter disconnect enclosures.... assume this is sufficient as the inverter (should be) certified as such. In a raceway or "gutter" box, i've been given the ok from electrical inspectors to bundle and keep the AC and DC wire bundles separate from each other. In a trench, since you are running separate conduits, that could be sufficient, otherwise the separation could easily be a layer of dirt or perhaps a pressure treated plank.
Good Luck. *Benn Kilburn * Partner, CSA Certified Solar Photovoltaic Systems Electrician, SkyFire Energy Inc 6706 – 82 Ave NW | Edmonton, AB | T6B 0E7 M: 780-906-7807 P: 780-474-8992 | F: 888-405-5843 | www.skyfireenergy.com [image: email] <b...@skyfireenergy.com> [image: facebook] <https://www.facebook.com/SkyFireEnergy> [image: twitter] <https://twitter.com/SkyFireEnergy> [image: linkedin] <https://www.linkedin.com/company/283735?trk=tyah&trkInfo=tarId%3A1408655033432%2Ctas%3Askyfire%2Cidx%3A2-2-5> [image: google] <https://plus.google.com/+SkyFireEnergy/> [image: SkyFire Energy Logo_horizontal] On Mon, Oct 5, 2015 at 8:45 AM, AE Solar <autonomousenerg...@gmail.com> wrote: > Wrenchers, > Anyone know of code violations associated with running DC conduit in the > same trench as conduit for AC secondary?
