What do you mean.."You guys are great, thanks for your help in confirming what we suspected. The poles are required to be grounded directly so the EGC is not at issue"
Some specs require a driven grd rod at each pole...this however is in addition to the EGC that you run with the circuit.
I'll second or third what the other esteemed members stated regarding the EGC upsizing, and increasing the neutral conductor.
