When we put in the new, 200A service, I ran about 110-120 feet of 4" PVC 
conduit from the pole to the service entrance.  I rented a skid steer 
trencher with a platform on the back for the operator stood on, from an 
equipment rental place. Home Depot, or :owe's didn't have one that big. 
I don't remember the width of the trench, but I do remember breaking two 
shear pins getting diagonally across the driveway.  I had a good size 
messenger cable in there too.  I remember how happy that made the power 
company crew. They just had to put lots of snot...er cable pulling soap 
on the three 00 Cu cables and pull.  The did pull their own, still 
larger, messenger cable in first though. That was not a 5 minute job <:-)
