Electrical Installations: Pull Box Sizing Pull Box Dimensions. This pull box must have a height of 18” and a width of 20”. For the angle pull, the distance between the entry and exit is 18” (six times the conduit dimension, which is 3”). Importance of the Design Procedure. While pull boxes are convenient, keep in mind that they require materials and labor, and can increase project cost if used excessively. How to Size Pull Boxes | eHow The National Electrical Code (NEC) mandates specific sizes for pull boxes, determined primarily by the conduit, or raceway, sizes and pulling scheme. Three types of pulling schemes are used: Straight pulls, which travel straight through a pull box; angle pulls, which make a 90 degree angle; and U pulls, which turn 180 degrees to re enter the same side wall. Sizing Junction Boxes | EC&M Pull box sizing (Example 2) Let's say a pull box contains a trade size 2 and trade size 3 raceway on the left side, a trade size 3 raceway on the top, and a trade size 2 raceway on the right side. The trade size 2 raceways are a straight pull, and the trade size 3 raceways are an angle pull. How to Calculate Underground Pull Box Sizing For example, if you have a pull box with 1 3'' raceway on the left, 1 2'' raceway on the left 1 2'' raceway on the right, and 1 3'' raceway on the bottom. So you have a 2'' straight pull and a 3'' angle pull. STEP 1: Determine the size of each raceway you will be using. NEC Requirements for Sizing Junction Boxes and Pull Boxes ... Conductor damage during installation is one consequence of under sizing junction and pull boxes. This damage is often not apparent until post installation cable testing. Then, after the boxes are replaced, the defective conductors are replaced. This is an inefficient and expensive way to do an electrical installation.

Pull and Junction Box Calculations, Part VII When determining the minimum size box for conductors 18 through 6 AWG, the sizes and numbers of conductors are needed to calculate the minimum size box. The sizes and numbers of raceways must be known before sizing boxes containing conductors of 4 AWG or larger, under 600 volts. Which Size Box? | Electrical Contractor Magazine Considering an angle pull, if the enter and exit walls contain raceways of 3, 2 and 1 in. respectively, multiply 3 inches by 6, and add 2 inches and 1 inch. That equals 21 inches. Therefore, the size box for an angle pull is 21 inches by 21 inches. As another rule of thumb to size a box for an angle pull, multiply the largest of the raceways by 10.
