Connecting 6/3 UF Flat wire?


We have flat 6/3 UF wire that we will be putting in the ground for about a 400 ft run to a pump for irrigation purposes. There is actually a control box at the pump that is already wired to the pump and a control box at the house that is wired to the electrical panel. We went with 6/3 wire for the voltage drop but as you know the flat wire is about 1 inch wide and the control boxes do not have 1 1/2 inch knockouts for the conduit.

So we are trying to figure out the best way to go about this. So far the best we've come up with is putting junction boxes near both control boxes and downsize the 6 gauge wire to something like 10 and then run it in smaller conduit into the control boxes. The control boxes have poles (see attached image) that we can simply connect female connectors to.Name:  pic.jpg

1st question - is this the best route to take or is there something we haven't thought of yet?

2nd question - If this is the best route we are having trouble finding connectors to downsize the 6 gauge wire to 10. What is the best way to do this?

*EDIT - suppose I could always drill larger holes in the bottom of the control boxes. I'm having trouble finding female terminals/connectors to attach to the poles though for 6 gauge wire.

Thanks for any help.

Drill or punch a larger hole for the connectors.

Large blue or grey wire nuts are good for 2 #6 or smaller.
