Word of Mouth for quality work runs far and wide, but dispersed.

Routing three 10/2 UF cables through and out of a house interior wall down the exterior of the wall, Using a PVC 90-degree elbow, down exterior wall through the roof of a connected shed.
This is a common wall shared by the shed and the house.
PVC conduit will be used beginning at the exterior wall until the cable reaches each of the appliances.
Would it be wise to use one elbow exiting the house wall, in one PVC conduit pipe down the exterior portion of the wall, or three separate elbows, and three separate conduit pipes.
Because this is a makeshift shed, PVC conduit will be used even after the conduit branches off in route to each other appliances.
When three cables run through the elbow and PCV pipe what size conduit should be used?
When one cable runs through the PVC elbow and conduit what size conduit should be used?

Any tips and suggestions would greatly be appreciated, thank you
 
The appliances will be located inside the shed,

The appliances will be located inside the shed,

The appliances will be located inside the shed, the cable will route down the interior wall of the shed
 
Ignorant Brit strikes again..........:D
What's 10/2 UF?
I assume 10AWG, 2 core.
But I'm stumped with the UF.
Anyone care to step in with some wisdom?
 
Assuming this shed is not attached to the building the supply is coming from you need to scrap you entire plan.

Please review 225.30 with your journeyman.
 
As previously stated, the wall are common wall attached to the property

The wall is a common wall attached to the property, would it be wiser to route to conduit separately from beginning to end. If combined into one conduit pipe, what size conduit should be used?
 
The conduit needs to be a certain size to disperse heat and expansion, I can't rememb

See 310.15(B)(3)(A).....

I know you're worried about damage, but why mess with UF in the conduit?

If you're gonna be using the conduit anyway, better imo to ditch the UF and just do pipe and wire.
 
I believe code states that if any portion of the wire is outside witch

I believe code states that if any portion of the wire is outside witch

I believe cold states that if any portion of the wire is outside it needs to be in conduit, the upper portion of the cable before it enters the roof of the shed will be outside.
Thanks 4 your post
 
I can't bring the cable in below the roof from the house because below

I can't bring the cable in below the roof from the house because below

I can't bring the cable in through the wall directly below the roof because on the other side of the wall at that level there's wall tile I don't want to damage

Code doesn't says UF must be installed in conduit if outdoors, only that it isn't permitted where subject to physical damage- see 340.12(10)

My point is that if you want conduit anyway- just nix the uf altogether, do pipe & thwn and be done w/it.

And I disagree about that being an exterior location per your description- but that's another topic

How are you feeding this? If your are picking up an nm somewhere in attic or whatever, just do a JB at that point and connect your pipe(s) and twhn to that, after pipe is run thru soffit etc....

Sounds more like you possibly are installing a protective sleeve more so then a complete raceway system?

Ampacity adjustments apply because you have them grouped/bundled together but won't change size of 90 degree conductor needed with only six current carrying conductors involved. Ambient temp adjustment could apply depending on circumstances.

I would suggest using NM and just punching through the common wall under the shed roof. There is no reason to make this any harder than it has to be.

I thought that too at first with this being, to me, a dry loc, but the inside of the shed may be unfinished and nm may be be subject to physical damage.

So what? The UF would need to be protected inside the shed in the same way. No reason to run conduit and UF for no reason. If you want to run the NM or UF in conduit once it gets inside the shed to protect it, no reason you have to run it that way to get there.

The problem here is that the op hasn't told us how or from what he plans to feed this setup....

If he is using planning on using UF to tie into ckt inside of house and then that from under soffit on outside of house and then into attached shed?
Going straight thru common wall of house/attached shed ( he doesn't want to do that b/c of tile damage, or so he says) to feed all this?

Using UF w/ conduit instead of conduit w/ thwn is a bad idea here: he says he needs 1 UF to feed 3 cables or 3 UF individually run, and he wants to sleeve them but exposed UF running along a soffit or from where ever etc.... down into a pipe/side of a building looks like crap.

Picking up his feed inside the house (where ever that is-prolly attic/ could be UF poking out of wall of house.....) piping from JB at that point (and using thwn instead of the stiff UF) then going to soffit/elbow/LB at outside wall etc, then piping from there into a JB inside this room/shed, then piping from there and hitting what he needs to, is basically the same amount of labor, looks better, and also allays the concern about "subject to physical damage".
