[TowerTalk] 220v trench proximity to 7/8” feedline trench?

There is nothing wrong with using the same trench, why do double work?

Need some guidance as it relates to the proximity of a new 220 V power  
line (trenched and in PVC conduit) running to my crank up tower (3 HP  
motor) about a 500 foot run from my barn and 2 runs of 7/8” hardline  
(partially trenched through fields and not through the woods) all  
terminating at the tower base.

What is the minimum that the 220v trench should be separated from the  
7/8” feedlines trench? they will run parallel for about 250’ then go  
their separate ways, 220V to barn, 7/8” to the shack.

Thanks in advance
