I am planning to add a (GFCI) receptacle on a fence post, which is 45m from the garage (power feed). I plan to use NMWU 12/2 cable run in a PVC water pipe (or flexible cable protector) and the risers at both ends will be rigid PVC conduit. I plan to use 12ga to allow for future extension down the laneway (100m or so). The 45cm-deep trench will be dug with a mini-ex in an area with no vehicle traffic. I live in southern Ontario.
Question: How is the wire from the ends of the pipe to the conduit to be protected? (Do I leave it with a small loop or wrap it in something?)
Edit: I found a source of flexible PVC electrical conduit, so I can use it and connect the ends to rigid conduit. (This sort of obviates my question, though.)
