How do you connect a LB conduit body?

Hello!

I've started working with conduit and am stuck on this part. One part of the LB goes down/up into conduit. I got that. For the part that's attached to the house, it looks like it is made for conduit to come out of it. Where does that conduit go? How far into the wall? Does it just end and then wire starts, or is required for the conduit to run all the way to a junction box? I can't find a good picture or video anywhere.

I appreciate your help and info!

Regards,

Leaning

IF you are using individual conductors (wires) and not cable then the conduit must be continuous from one end to the other. If you are using the conduit solely as mechanical protection for cable then you can use just a stub of conduit in the wall.

Remember, you cannot use type NM cable outside even if it is in conduit.

Isn't this the same thought process? Trying to keep it all together. http://www.doityourself.com/forum/el...utlet-box.html

Chandler,

It is, but I'm also looking at running conduit out to a light post and for a pool. That thread was specifically about the porch light. Researching conduit, I kept seeing references to LB bodies, but didn't know what they were talking about. Then all the pictures of them I can find are of one of them lying on a table (not connected) or already attached to the house showing the conduit coming down out of them, but not the one going into the house. I couldn't find anything what is happening with the end going into the wall, so I thought I'd ask. I didn't want to turn that thread into a purely LB body discussion. It's your call. I'm good either way. Furd answered my question, and then also supplied that extra about not using Romex inside damp/wet location conduit (334.12), so I have to go grab some different wire (THWN). I love this forum, but every time, it is guaranteed to send me on another trip back to the hardware store.

An LB is just a way to make 90 degree turn in a conduit system . It also serves as a pull point between bends.

Instead of using an LB you can use a weatherproof box. You can bring NM-B (romex) in the back where it attaches to the house and then come out of the bottom with PVC conduit and THWN.

The "LB" is for making a sharp "L" shaped turn in the conduit, and the conduit port exits out the "B"ack of the fitting. There are also "LR" and "LL" for right turn and left turn. Any of these fittings does need to remain accessible, because they are impossible to pull wires through without opening the access door. They also must have a conduit in and a conduit out just like any other bend.
