We used to just bundle the PV cables and secure them close to the
pivot point at both the rack and the pole with insulated wire loom
clamps. We always made a big enough loop to handle full
articulation, but not too long so they wouldn't catch on the
Combiner box, etc. We also started using braided ground strap,
instead of stranded #6. Braided is made for movement, stranded #6
would strain harden and break off at the connector.<br>
I'm not sure how flex conduit would do. It definitely could break
out of a plastic J box, I would think. The back and forth motion
eventually wears out things not really made to move. I had lots of
trouble with this issue.<br>
Finally, don't be greedy on tracker settings, I'd keep the total
range of motion to less than a full 180 degrees Azimuth, and
probably limit the tilt some too. <br>

</div>
<div>I'm looking for advice on the best way(s) to secure PV
source circuit wiring on a dual axis tracker. I've never
wired one up before and it seems tricky. This particular
tracker is 12 modules, 3 strings. Is it best to run a
flexible conduit up the pole and leave plenty of excess
conduit to create large loops that fluctuate in size
throughout the day? What are some other ideas? How do you
avoid abrasion over time? </div>
