I trenched mine as well. It was about 250' worth. Used a ditch witch on it. Worked well, but was A LOT of work. Red clay is very hard. My electrical guy said it needed to be a foot deep. Inspector came after I dug it and said it needed to be 18" deep. Had to dig the extra 6" by hand, as the ditch witch was borrowed and I had to give it back.. That SUCKED. Dig it deeper than needed, as the ground tends to fall in some over a day or two, if you can't get it inspected the same day as you dig it.
