Hello
What did you or would you do?
I am planning on a 2 foot trench but are those PVC conduits with the expansion joints really needed? Direct burial electrical wire OR THHN / THWN ??
Also should there be stones in the trench for drainage?
THW = Thermoplastic PVC-insulated building wire, Heat resistant +75°C/+167°F, for Wet and dry locations, flame retardant
THHN = Thermoplastic PVC-insulated building wire, Nylon jacket, +90°C/194°F, 600 V, for dry and damp locations

Here is what some people did.
