Emt offset multiplier chart

Example: As an example, the offset distance of an obstacle is 2” and the distance to obstacle’s center point is 20”. The installation allows for a 45° saddle bend. Note: The choice of degree is usually the installer’s choice and most of the time the installation location will determine what degree will fit. After watching this video, you should be able to calculate ANY multiplier on an offset without the use of a chart. This formula works on ALL conduit types and ALL conduit sizes. If you have a

Offset bends are used to move a run of conduit from one plane to another. An offset is normally used to bend the conduit around an obstruction, or to relocate the conduit close to a structural member to make it easier to fasten the conduit. Figure 2 shows an example of an offset bend. Layout.

Use the offset multiplier to find the distance between the two bends. Each angle has its own offset multiplier, listed below this step. Multiply this value by the offset depth to get the length between your two bends. For a 10º angle, multiply the offset depth by 5.8. For a 22.5º angle, multiply offset depth by 2.6. The offset bend is used when an obstruction requires a change in the conduit’s plane. Before making an offset bend, you must choose the most appro- priate angles for the offset. Keep in mind that shallow bends make for easier wire pulling, steeper bends conserve space. The EMT bender has degree marks on it for making precise 10 °, 22½°, 30 °, 45 ° and 60 ° bends. There is not a 90 ° mark on the bender. The 90 ° bend is made by bending the raceway until it looks like the raceway is bent to 90 °. This will get easier with experience. The EMT bender also has several marks that are used to line up Offset bends are used to move a run of conduit from one plane to another.

I would like to print out and laminate a copy of it in a pocket size format so I can start carrying it with me every day. I round to the 1st decimal place and I know the common ones but I wanted to check myself so I listed all from one chart. Tom.

Calculator Shrinkage Multiplier = Shrinkage / Offset Height and largely the result of Benfield's Tables as published in the Benfield Conduit Bending Manual.

To Determine Offset Loss (amount that conduit is shortened by bending an offset) After determining angle to use, bend this angle in a piece of scrap conduit. Measure from the You can also use the inverse cosecant on your calculator. Example: To find unknown: Multiply known figure by the multiplier for desired angle. We know that A = 4 and B = 15. We also know that tan (d) = 4 / 15, or .2666. The calculator tells us that the inverse tangent of .2666 = 15º. At the same time, we can find the multiplier of a 15º bend by dividing one by the sine of 15º; the answer comes back that the multiplier for 15º is 3.86. Using the Multiplier When Bending an Offset The multiplier is the number of the measured distance of the offset it is multiplied by to obtain the distance between the two bends. You should memorize this number for the common bends of 10, 22, 30, and 45 degrees. As an exercise, consider an offset of 12" using two 22º bends. Again, C = A / sine(22º). Note that this can also be written as C = A * (1 / sine(22º)). The sine of 22º = .3846, and 1 / .3846 = 2.6, which is the familiar multiplier for a 22º offset. This kind of math is where those multipliers come from! Example: As an example, the offset distance of an obstacle is 2” and the distance to obstacle’s center point is 20”. The installation allows for a 45° saddle bend. Note: The choice of degree is usually the installer’s choice and most of the time the installation location will determine what degree will fit. After watching this video, you should be able to calculate ANY multiplier on an offset without the use of a chart. This formula works on ALL conduit types and ALL conduit sizes. If you have a If we made two 90 degree bends at 60 inches apart that should give us a 60 inch offset if the cosecant is the correct multiplier. However, the calculator says the distance between bends should be 51 7/16 inches and the multiplier is 0.857. Using the cosecant as a multiplier would make our offset 60 - 51 7/16 or 8 9/16 inches too high.
