John,
Here is another fight I see happening around here PVC conduit is used around here everywhere. Shall not be used
"Where subject to physical damage". As per sec.352.12 (C). So some EC's are running PVC around the house on the outside in a flower bed and were being failed. One AHJ says that he wouldn't allow sch 40 PVC used anywhere below 8'. Another is only allowing sch 80 PVC above ground and you have to prove to this AHJ that all fittings, sweeps, and condolets are sch 80.
