WebDetermine the size of each raceway you will be using. STEP 2 : Determine if you need a Straight or Splice/Angle/U Pull, as you need to use different formulas. STEP 3 : Calculate the Horizontal Dimension: Straight Pull: Left to Right: 8'' x 2 = 16''. Right to Left: 8'' x 2 = 16''. Your pull box must be at least 16” wide. WebIf there are two rows, perform two box calculations. The row requiring the maximum distance is the minimum length for the dimension being calculated. For example, the front row for the right side of a box contains a 3-inch and a 2-inch raceway. The back row on the right side has a 4-inch and 1-inch raceway entering the box.
