The following sentence is an excerpt from 2014 nec 214.28(a)(3)
Listed conduit bodies of dimensions less than those required in 314.28(A)(2) having a radius of the curve to the centerline not less than as indicated in Table 2, Chapter 9 for one shot and full shoe benders, shall be permitted for installations of combinations of conductors permitted by Table 1 of Chapter 9. These conduit bodies shall be marked to show they have been specifically evaluated in accordance with this provision.
Question 1. What does this listing look like on a conduit body? Is it a number or sentence or something etc?
Question 2. What is the Radius of the curve to the center line? How do you measure the "Radius of the curve to the center line"?
I know how to find the radius of a 90 degree bend in conduit. Measure from the center of one plane of the conduit up to where the conduit starts to arc in the perpendicular plane or using a math formula that uses a measurement across the radius and from the center of that measurement down to the center of the radius.
