Electrical conduit bending chart.
Conduit bending is one of the first skills learned by new apprentices in a commercial or industrial shop. They learn to use multipliers for 15°, 30° and 45° for offset bends. Most settle in on the 30° bend since the multiplier is 2. It makes the math very easy. However it makes for less than aesthetic appearance if the offset is less than 6".
Explain the methods and reasons for cleaning conduit. Identify benders and their uses. Define the common markings of a hand bender. Measure for and make a 90 degree bend. Identify an offset bend and its uses; Make an offset bend using an offset chart. Identify a saddle bend and its uses; Make and use a three and four bend saddle. When it comes to electrical installations and appliances, safety should always be the top priority. One critical aspect of ensuring safety is choosing the right wire size for the a...After the first 90° bend has been made, measure to the point where the back of the second bend is to be, “B”. Step 2. Measure and mark your conduit the same distance, mark “B”. Step 3. Align the mark on the conduit with the Star-Point on the bender and bend to 90°. Star-Point on bender must be referenced for accurate bends.Conduit Bender Diagram. A = Rim notch or teardrop -- Locates the center of a 3-point saddle bend. B = Arrow -- Used to line up the offset and outer marks for saddle bend. C = Star -- Indicates back of 90° bend, for back-to-back bends. D = Marks -- The degree marks indicating the angle of the pipe bent.
