Underground wiring - well pump
Hi
I am trying to run this AWG 6-2CU UF-B underground feeder cable from the basement to an outdoor well pump controller. This is a three wire (two isolated + ground) cable that is to be connected at 240Vac from the main panel and routed out for about 200ft. The controller is supposed to limit the current to 20A. I had the 18" deep outdoor trench dug, and I would like to protect the cable on most of its outdoor length. I read however some post (not on thi site) stating that one cannot run underground wire through conduit on the entire length of the cable because of possible cable outgasing. I still want my cable protected though, for future landscaping projects. 1. If I want to use some plastic pipe to protect the cable how often should I cut the pipe then? 2. What less expensive options do I have trying to protect the underground cable? I am also contemplating running in the same trench (at 8” depth though) an irrigation pipe. 3. Would this create any issue from an NECode stand point? Thank you for help |

You certainly can put that cable in conduit, problem is it will need to be pretty big, like 1-1/4 or 1-1/2 inch. If it were me I'd use 1-1/2" PVC Sch80.
6/2UF cable is quite large. No problem from an electrical code standpoint to have the water above the electric. |
