I have rewired my house and my shop, but have never run any underground wire. A book I bought says to run it without conduit. A local electrician says to use conduit. It'll be about 25 ft. No vehicles will go over the area. I bought outdoor wire, rated to be buried. I would like another opinion.
What will the circuit be used for & where will the wire be run?
If GFCI protected before it goes into the trench then you can go to 12" for a 20a circuit
I do conduit also - just better IMO
