I've just ran power to 10 new irrigation center pivots. I drove all rods vertically but talking to the other guys, they said they've just buried them before. 250.53(G) 05 code, the way I'm interpreting it says I can't bury them unless rock is encountered when driven, is this correct? The ditch next to the pivot is open making it effortless to bury them. Do they actually enforce this in your area? Thanks.
