Conduit box hole size --IEC frame
(OP)
If given a IEC Frame number, let say "132S", how do I know the size of threaded or clearance hole for external conduit entrance (expressed in conduit size ) to terminal housing?
Any place to check it out?

on the Reliance motor catalog->IEC Quick reference chart->Size "XX" means the conduit box hole size.
Frame 132s, size is 32mm, but actual measurement is 25mm
Frame 180m, size is 40mm, but actual measurement is 50mm
The motors are Reliance motors.

IEC frame specifies conduit box hole , if the frame is 132s,then the conduit box hole size should be one specified size only.
But my measurement different from the Reliance catalog.

Are the motors new, has somebody re drilled the 180 frame to accept bigger cables??
