Thank you all for the very informative contributions to this thread. I've learned a great deal.

I assumed I'd be using direct burial armoured cable for the mains install so figured a conduit would be unnecessary. I just wanted to put a raceway in now so I could have an electrician run the wire later. According to "bcsa_handout_-low_voltage_service_-part_1_2" there is a 600 mm (24") minimum for cover over a raceway that will be subject to vehicular traffic unless there is extra protection afforded by solid planking, poured concrete, or concrete slabs in which case cover can be as little as 450 mm (18"). I read somewhere that Sh 80 PVC conduit is required for the 24" of vertical cable at the ends of the trench but can't find the reference now. In any case that seems like reasonable protection so I plan to switch to the sch 80 at the ends. I do want to be code compliant. For the small extra cost I'll do the same for the 1 1/4" phone line conduit.
