What is the difference between a junction box and a pull box?

Pull and junction boxes As a rule of thumb, pull boxes are used when conductors are pulled straight through a box and terminated down-stream. On the other hand, junction boxes can be used for splicing or tapping conductors.

What is the purpose of a pull box in electrical?

Pull boxes are used along with conduit to simplify wiring installation, hence their name. They are made of sheet metal, cast metal, or a non-metallic material, and provide a way to pull conductors long distances without placing excessive strain on the wire or insulation.

How do you size an underground pull box?

Straight pulls need 8 times the the diameter of the largest conduit/raceway. In this case, simply multiply your largest raceway size by 8, and that will give you the minimum length for your box.

How many wires are in a pull box?

For example, the smallest 2-by-4-by-1-1/2-inch-deep box can comfortably splice only two cables (four or five conducting wires), while the largest 4-by-4-by-2-1/8-inch-deep boxes can handle as many as four to six cables (up to 18 individual conducting wires).

How do you measure a pull box?

For straight pulls, 314.28(A)(1) requires that the length of the box be at least eight times the trade size of the largest raceway. To correctly apply 314.28(A)(1), just multiply the largest raceway size by eight. The box must be at least as long as that number.

Can you splice in a pull box?

No, there is no requirement to make splices in a junction box. However, if you’re not making any splices, and never plan to. You can use a conduit body, instead of a junction box.

What is the minimum length of a straight pull for a pull box with two 1?

The length of this pull box must be at least 24 inches (see Figure 7). Provided the box only contains straight pulls, boxes having more than two raceway entries are calculated exactly the same. For example, three raceways will enter the left side and three raceways will enter the right side.
