The best way would be to run pvc non metallic electrical conduit from your
service panel to the end point. Use weather proof LP fitting at your 90
bends to make wire pulling easier. Make sure your conduit is at least 24"
under ground or more if your code requires. You'll need to secure the
conduit with plastic straps.
This link shows type fittings that should be used.
inch conduit should be fine for 3 #8 THHN wires. A weather proof fusiblesafety
disconnect should be install at the remote end of your conduit run."Frank
