One usual misinterpretation comes from something very similar to what happened to you. Someone is looking for a rule on bending radius and they come across this but if you look above it it is in Part ll and that says "over 1000 volts. " This is often missed because it isn't in the section buit that section is under Part ll so it applies only to over 1000 volts
300.34 Conductor Bending Radius. The conductor shall not
be bent to a radius less than 8 times the overall diameter for
nonshielded conductors or 12 times the overall diameter for
shielded or lead-covered conductors during or after installation.
For multiconductor or multiplexed single-conductor
cables having individually shielded conductors, the minimum
bending radius is 12 times the diameter of the individually
shielded conductors or 7 times the overall diameter, whichever
is greater.
