What is the bending radius for steel conduit?
Our conduit size should be large enough for a short pull. Next, we check the bending radius from the cable manufacturer, and find that they require a minimum bending radius of four times the O.D. of the cable: 4 x 0.59 in. = 2.36 in. radius (minimum).

How do you find the radius of conduit?
Halve the measurement of the diameter to calculate the pipe’s radius. For example, if the diameter is 20, then halving that length produces a radius of 10. Divide the circumference of the pipe by π, which is a mathematical constant that begins with 3.14.
