[RE-wrenches] AC/DC in Same Trench?

For some upcoming utility-scale projects our design team is wondering about placing direct-bury AC and DC circuits in the same trench. - Firstly, is this even *Code*-permissible? - Secondly, are there any common sense reasons (induced voltage/signal interference/etc) for not doing this? Thanks, Co

No problem with same trench, the requirements are that they are not in the same raceway. On Wed, Dec 28, 2016 at 1:37 PM, Corey Shalanski wrote: > For some upcoming utility-scale projects our design team is wondering > about placing direct-bury AC and DC circuits in the same trench. > - Firstly,

Re: [RE-wrenches] AC/DC in Same Trench?

Also, you didn't specify, but AC and DC are specifically allowed in the same raceway per 300.3(C)(1). Only If the DC circuits are PV source or output circuits, then 690.31(B) prevails, which says they can't share a raceway. But again, as Chris mentions, this restriction does not apply to dire

WrenchesAs a matter of practice, we always use conduite, never direct burial, always copper too, we have had AC and DC in the same trench but with space seperating the conduits and have had no issues with noise or JHA. As a safety issue we would not risk direct burial of high voltage DC re

I fully agree that some sort of display/interface is crucial to making our lives easier. We do many remote applications, as well as just having horrible internet service in our area and many installations have no---> internet, cell service, WiFi, etc.. it would be a shame to limit ourselves.. Joe
