Pull Elbow in stud bay?

[RonRock]

I have underground conduit coming up and through the 2x4 stud wall with an LB outside. I would like to keep the conduit in the stud bay to eventually be drywalled over.

A 90 has too wide of a sweep and pushes the conduit proud of the wall. So can I use a pull elbow, or an LB in the stud bay? That would keep the conduit inside the studs.

3/4" PVC with 4- #10 conductors. Going to a disconnect. No splices in the conduit.


Or can I heat and bend the 90 to a tighter radius so that it is close enough to be in the studs?

No, you CAN'T "bury" a box, LB or a pulling ell behind a non-removable finish. There needs to be ready access to the removable cover.

I think he meant to say can't...

 

[grounded-b]

Yup. corrected the post !!

 

[wyliesdiesels]

thats a negative ghost rider

 

[RonRock]

Ok. Thanks.

I know that you can't cover a box. And that makes sense. Just wasn't sure about an ell.

You might be able to use back to back 45s. Get rid of the outside LB and go straight into the panel. Requires drilling the entrance hole at a 45* up angle.

There's also a 3/4 flex elbow assembly, Carlon UAFAE, if you can find it.

Just run the conduit up higher outside and go straight into the back of the box.

If it's a pull elbow, with no internal connections, is that still the case?

Pulling ell's and conduit bodies need to be accessible. You have to be able to get the cover off to be able add or remove the wires

Got it. IANAE. On my phone so haven't been able to pull codes, but...

Once the wire is pulled, and if the pulled wire is continuous (no connections made up in the conduit body), then what's the logic to require future access?
If you cemented the cover, wouldn't it just serve as a 'funny bulge' in the conduit (that at one time facilitated the ability to pull the wire). Granted, it would be a challenge to add in the future, but...

I thought you could not make connections inaccessible, but a continuous wire should not be an issue.

Again, IANAE.

Look at 314.29 of the 2017 NEC

Its not like a conduit run with 90 and 45 bends. Just because there are no splices doesn't make a difference. You have to be able to get the covers off for servicing the conductors, meaning replacing or adding to it. You would never be able to pull wire around those fittings in one straight pull. Is no different than when the wire was first installed, it had to be done in steps with the covers off. You are not even allowed to bury a greenfield 90.

Just looked a job the other day about adding some wires to a existing conduit from the house to the garage. Same situation, back to back LB's at the garage. The inside LB was drywalled over. Said I would have to cut the drywall and put a access panel in to get to cover..

As Bert said, just run the pipe up higher and LB into the back of the panel.

Yeah I thought about running the pipe higher. I've already drilled through the wall. I left it as low as reasonable, I hate to see pipes running up a wall.

The reason for my question was as Gutman stated.

I'll probably just leave the 90 and leave it sticking out. Although I may run the conduit to the back of a box, then up. Leaving the cover plate outside of the drywall and accessible. I need to size that up to see if it will fit.

 

[Innovate1]

You could use back to back LBs and put the cover of the inside LB flush with the inside drywall. The conduit would be just behind the drywall. I have one like that in my garage with 2 x 4 walls.

 

[mobetta]

shouldnt be terrible hard to set an LB so it gets mudded around and kept accessible
or use a pvc J box, feed in the back and out the top, add a blank cover

my garage has 2" running up into the stud cavity and a 12x12x4 J box(6x the conduit size min) that finishes off flush with the drywall.

(200 amp service to garage, 100 amp feed to house- meter and panel at opposite end from house)

 

[sky jumper]

or just build a small removeable panel in the drywall, or leave a hole and cover with a faux furnace return vent, etc. many ways to skin it. or just cover it with drywall and never think of it again. sure you'll have to cut the wall open if you want to pull new wire, just like if it were romex...

I understand a pull elbow that is being used due to the limitations on 90's between access points. So, if there are 30 90 sweeps your next 90 has to be an accessible pull elbow. But, if he is using the pull elbow as the only 90 between 2 other accessible boxes, could it then be covered as it really just functioning as conduit?

If it has a removable cover, it has to accessible

Glue it on?

No. you can not "bury" any device with a cover.

How would the future electrician ever get a fishtape through a pull ell, if the cover wasn't removable?

If he was lucky and he knew the pull ell was buried, he might use the existing conductors to "possibly" pull new wires in. But that doesn't justify "burying" it.
