My New House & Workshop

[Curious Hound]

I should have read @Curious Hound post first, but these are not considered bends.

So between the one coming out of the house and the one going into the shop, the only bends you need to worry about are the ones underground.

I just read back through his description. He’s still going to need a pull point somewhere even if he used LB’s where he went through the walls into the house and shop. If I was doing it, I probably would have cheated with some gently curving trenches instead of some if those 45’s, if possible. In the Texas sunshine, that conduit would have layed in a gently curved trench very easily.

Well, I have my trench all dug, but at the moment I'm kind of screwed.

The NEC says you can't have more than 360 degrees in bend for conduit.

The cable has to go from the subpanel straight to the wall, 90 degree down into the ground and turns 90 degrees away from the building for a way and the bends 45 degrees left and the 45 degrees right to go around the corner of concrete pad, and then makes a 90 degree right turn at the other corner of the pad.

That's 360 degrees.

From there it continues and makes a 45 degree left, several more feet it makes another 45 degrees left (now it's at the corner of my concrete pad next to the house that I park on) and is heading for the house.

That's 450 degrees.

When it gets to the house it has to turn up 90 degrees along the house and then make a 90 degree left turn and head for the main breaker panel.

That's a total of 630 degrees.

I'm thinking I need to put a pull box in the ground where the 5th bend would be (the 3rd 90 degree bend). From here I'd have a total of 270 degrees of bends left.

The pull box is something I just became aware of. Now I have to figure out what to get, where to get it, and how to install it.

They are not cheap. We use these at work. Remember, any box has to be accessible.

Both if these are inexpensive and easily attainable.

This is s sufficient box.

And this would make it easily accessible.

Next problem, finding a pull line steing enough to pull (3) 1 gauge wires through 2-inch conduit.

If you were closer. I still have my old synthetic winch line. When I build services we just ran a small nylon string at first. Then used that to pull a bigger 1/2" nylon rope. I would always stagger the wires when we tied them in. We had a small trick. If you know you have a lot of glue joint to pass. You can take a paper plate. Slice it from the middle to the edge. Then you can form a cone around the connection between the wires to help keep the flat ends of the wire from hanging on the joints. We also used to have a gas powered tugger at shop. If you have anyone close or who rents one. Makes it a lot easier on your back.
