Hello All,
Sometimes on our utility scale solar projects, #6 solid copper is specified by the engineer for grounding/bonding combiner boxes to racking system and it gets ran in conduit. Usually this is for a short run, such as to go from a weatherhead close to the rack to the combiner box a very short distance away.
I seem to remember that there was an exception or allowance in the code to allow for #6 and smaller to be run in conduit when run with PV source circuit wiring but I can not find it. Is there such exception and where is it? So far, we have never had trouble with this, but usually wires #8 and larger are supposed to be stranded when run in conduit.
