Direct Bury
Most utilities stop using conduit years ago where there is "dirt" above. They still use it under roads. I was looking at new construction in Sanibel and the cable contractor dug into a direct buried 7,200 volt line. It is rare to see the secondary voltage 120/240V in conduit other than the short run from the meter box to about 24" in the dirt. Talk to a SECO serviceman last year and told me they sometimes make "service taps" in the dirt to save the cost of a pedistal. We would never do that up north, but it snows up there. Conduit cost more money.
