Nov 17, 2022 · For instance, consider an electrical pull box with a 90 degrees having three raceways with 3”, 3” and 5” diameters. You should calculate the pull box size as follows: 6 multiplied by the biggest raceway diameter = 6 x 5” = 30”. Sum of all additional raceway diameters = 3” + 3” = 6”. Total = 30” + 6” = 36”. 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.
