Plus you eliminate the need for costly conduit elbows when you make your own bends. That is how many 16ths of shrink. If bending at 10 degrees, the conduit will shrink 1/16 for every inch of rise. Web when bending two or more offsets it is necessary to advance the centers of the bends for the progressive conduits in order to maintain an equal center to center spacing. Frequently asked questions (faqs) q: This page incorporates a comprehensive conduit bending guide and describes how to bend an offset using multipliers. Remember to ignore the shrink when working away from the obstruction, but be sure to consider it when working into it. The code further specifies that the total of all bends in a conduit run must not exceed 360°. Web you must also consider that the conduit shrinks due to the detour. Web there are shortcuts for a lot of the constants like shrink or multiplier that can be done on a calculator.
