What kind of conduit is recommended?


Like many in this thread I am running power (and a PEX H2O line external of conduit) to a shed that is 50ft from the house. I have dug a trench 18" deep all the way down to the shed and am ready for the conduit but have two questions about this: 1) My trench is not straight all the way and has off 45 and 90 degree turns. Is there a flexible conduit I can run? I like the idea of running a larger conduit than needed for future power needs. 2) Can I run the conduit, fill the trench back in, then have an electrician come run the wire if I don't do it myself? I'd like to get the trench filled back in as soon as possible but I don't want to find that the wire should have been run before filling in the trench.

More info:
- Can't imagine needing more than one 20 Amp line down there. Only for a light and a 250 Watt heat lamp for the chickens.
-Live in Pacific NW where I believe 18" is deep enough
-Plan on punching through house foundation to bring the power and water out.

Any additional adivise welcome.

Thank you.

Conduit must be installed empty before conductors are pulled in. No problem burying an empty conduit.

You can purchase pre-made elbows, in both 45 and 90 degree bends. Just be sure to use "sweep" bends (never use plumbing fittings on electrical conduits) and no more than 360 degrees total bends in any one run of conduit.

PVC conduit only requires 18" of cover, so your trench should be fine.

I like the idea of using larger conduit too. Maybe even an extra conduit left empty? Since you have at least one 90 and one 45 in this trench you will have a hard time getting a fishtape through it at 50 feet. If the 90 is at one of the ends you might be able to.
You will need a shop vacuum, roll of string and a sandwich bag. You will suck the bag through. Its real easy. They make a special item just for this. They are called conduit "mouses". It takes the place of the plastic bag.

I always run larger conduit
I also ran 3 conduit runs to my pool cabana
1 for electric
2 spares for phone, cable or Internet access

18" is deep enough for electric
But you want to run a water line?
I'm not sure what the frost line is out there...

PVC is pretty flexible but don't go all crazy.

3/4" will suit your needs.

Maybe. I don't like pulling wire in thru a homeowner installed conduit. It's not rocket science, but still..............
