For a few different commercial projects we have used strut as a raceway on 600v systems. Particularly helpful with Renusol tub racking as the strut connects the rows together and doubles as a nice raceway. Also particularly cost-effective for those of you who are doing EVERYTHING in conduit.
My question is that 384.10(4) clearly states 600V or less. I have a 1000V system, the question is simply does anyone know the reason why this is limited to 600v, and if there are any exceptions, either currently under NEC 2014, or planned for the future.
This particular design of this array would make strut a dream for wire management. All PV source circuit conductors are PV wire, and would enter conduit within 2' of leaving the various sub arrays.
Part of the issues is that we have long sub arrays, basically each sub array is 3x18; 3 columns - 18 rows, so they are long skinny sub arrays - 10 of them. The idea was to run the jumpers and home runs in the strut under the array. We are just trying to protect the source circuit conductors from damage between the inter rows of racking.
Open to suggestions here as well.
