Just to set the stage, I'm an engineer and not a contractor/installer:
My question is ... how do you measure the radius of a 90 degree conduit bend? Do you measure it the same as you would the radius of a circle or do you sort of measure the circumference of the bend?
I ask because I'm working with a spec that calls for 18" radius on 90 degree bends and the contractor has installed bends that either have a radius of 8" (if I measure radius the same as on a circle) or 18" (if I measure the circumference of the bend). The contractor insists that trades measure the circumference and I'm extremely skeptical.
