... for use in 1" PVC? Seems like it fits OK, except for the 90-degree bends... wanted to make sure it is code compliant.

UF cable can be installed in conduit, however, as you note, in a conduit that is not too small to allow for a smooth installation. Depending on the length of the conduit, and the friction of the cable inside the conduit, you may be better using a larger conduit to eliminate any friction.

UF cable contains 3 solid wires, whiich are not very flexible,and will cause more work than necessary, and can possibly damage the cable sheathing and the interior wall of the conduit. This damage may not be evident for a long peroid of time, as the moisture permeates the insulation causing it to break down, some day when you least need a problem, the cable shorts out and you have no power and a huge problem on your hands, first trying to trouble shoot where the problem is, and how to fix it.

What you are proposing is not very practical. This method is not done very often in the field, only possibly for short runs where a sleeve, for example, under a walkway or other paved area.

If you are planning to use continuous conduit, why not use individual stranded conductors? Much more practical and done every day in real electrical world.

UF cable is perfectly allowed to be direct buried in earth, minimum 24 " deep, and PVC conduit must be 18" deep. So you save some work by digging a shallower trench. And using individual stranded conductors will be so much easier to install, less chance of damage during installation, and will last indefinitely.

A large part of safe, practical electrical installations is common sense. As you noticed, #10-2 UF cable will not slide through the sweeps very easy. If you must do this,I suggest you use minimum of 1-1/4" PVC. If you need to use any smaller 1" PVC fittings, such as an LB, you will find yourself struggling to get the UF cable installed into it, and you will cause more damage than you can deal with later.

Hope this helps.

... the excellent advice. As I need to dig another trench nearby, I'll salvage the cable and opt for 1 1/4" PVC for a longer-lived circuit at 18 inches deep.
