Hi,
I have been working for a manufacturing company that refuses to believe that the minimum bend radius for a current carrying conductor (CCCs) at 60Hz is a necessary code. I was wondering if anybody knows of any technical documentation online that would provide the physics or mechanical rational for this code. Also, I have seen that infrared photos of CCCs with below minimum bends that show hot spots at the bends. I would like to see those photos again. The hot spots obviously indicate an increased I squared R loss and since the current isn't increasing the R must be. Or could it be a skin effect due to deformation of the strands? This is important to me because one of the issues I am dealing with is excessive voltage drop and I would like to know if these below min bends are part of the problem.
Thanks,
Bill
