underground conduit termination

[tyme2par4]

So I have a 8x12 outbuilding (actually a 2 story playhouse) that was built by a previous owner. It currently has 12/2 UF feeding it, but it is unprotected where it exits the ground. They also decided they would just throw a standard NEMA 5-15 plug on the end of the wire, and plug it into the exterior outlet on the house.
I'd like to fix the problems without digging up the entire 75ft run and laying conduit the whole way. Assuming the wire is buried at least 12", I believe I can run conduit from an LB on the wall down 12" to a sweep 90 on each end.

The question is, do I need something like the below on the end of the conduit? I'm guessing I'm not supposed to just leave the conduit open on the end.
I'd prefer to use PVC, as I have a couple pieces laying around already, and both ends are somewhat protected, and not subject to damage.

No connector needed, the 90 isn't needed either. I do like to run it in conduit where it exits the ground but it really only nessesary if it's subject to damage.

You don't have to follow all the rules for a normal conduit installation since this is just a sleeve.

Leaving the PVC conduit sleeve open on the ends is fine. Just deburr and smooth over the sharp edges.

Agreed, nothing required at the lower end of the conduit other than smooth edges.

Thanks! I've seen pictures with a gland at the end and wasn't sure if they were required.

I run these at the underground exit for direct burial. It helps keep the wire from getting scratched up when pulling bigger stiffer wire.

Make sure its a GFCI protected circuit as its so shallow.

Honestly, I have no idea how deep it actually is, but it will be. Either on a GFCI breaker, or the load side of the outdoor outlet.

NEC Code states that UF cable should be 24" below grade or 18" below grade with a minimum of 2" concrete cover. The sleeve you want to install should extend to that depth as well to keep future owners from striking the cable while digging around the cable location.

As others have noted, the circuit should be GFCI protected as well.

If buried at 24" the circuit does not have to be GFCI protected at the source. The circuit can be buried 12" if 120V and 20A or less and is GFCI protected at the source.

beat me to it
single circuit 120v exception to the burial code

I wouldnt do any substandard "feeds" to a kids playhouse.
can what ever is being powered out there be done with low voltage?
perhaps LED and solar panels,if you dont want to replace the romex

The only thing out there now is a single outlet and a light. Everything will be up to code as soon as I replace the plug on the end of the wire. It also has a 2 slot breaker panel in the building, so a second layer of protection.

That 2 slot breaker panel, does that get considered a sub panel being detached structure, with grounding rod requirements and 4 wire feed?

I don't believe so. It's only 120V feed.
