Three 1/2-inch EMT conduits start at the box on the top left and must clear the junction box on the top right. Notice that the lowest offset, the one in Conduit A, has been pre-positioned to make the end of the bend align with the left side of the 4 11/16-inch box. The bend angle will be 30°. In order to determine the amount of offset rise needed, a level is extended from the top of the 4 11/16-inch box to the box on the left, and then a measurement is taken from the bottom of the level to the lowest connector.How much offset rise is needed to allow the bottom conduit to go over the top of the 4 11/16-inch box? Note: The values for this question will be used in additional questions.
