Re: Minimum wire bending radius
It is also assumed conductors listed in Table 310.13 will be installed as part of a Chapter 3 wiring method. This includes Articles 312 and 314 which specify the minimum distance relationships of conductors or raceways entering various enclosures; as in 312.6 or 314.28.
For equipment enclosures Articles 408 and 409 specify wire bending requirements.
In other words, the requirements are not placed on the 600V conductors themselves, but the wiring methods or equipment.
