"...Shedule 80 is used more for exposed work, i.e., that is likely to be subject to damage."
ShockMe77: "Like, for instance,..."
Like anywhere aboveground, duh.
In our neck of the woods, we run Sch. 40 underground, but where it exits the trench, we switch to Sch. 80, anywhere up to 8' above the ground. This is what the AHJ demands.
And regardless of how our AHJ differs from yours, Tesla, refer to NEC 300.5(D)(1) & (4), NEC 300.50(B), and the 2004 UL WhiteBook.
So unless the definition of a "bollard, etc." is the same definition i would find for Schedule 80 PVC, I'd had to conclude that Tesla is in violation of the NEC when running Sch.40 where "any pipe is at risk for damage."
