We run Sch 40 PVC underground, unless we are going under a road or through a lot of rock, then it’s back to the Sch 80. We also run a #4 bare solid copper next to the conduit, more earth contact the better, it is nice to set the ground rod in the vault too.

Typically in a system where there are or has the potential to<br>expand into more than the original pole mounted array we run a couple of<br>main PVC conduits underground to a concrete vault, like a C-9, C-24, or<br>maybe even a C-30 vault. From this vault we distribute the conduits to each<br>pole mount, or in a larger field like the 8 poles you're mentioning we might<br>go into a second vault closer to the other end of the field, then branch out<br>to each pole from it too. We use PVC underground, Rigid metal through the<br>concrete and up the pole.
