Flexible connection fittings support

Where do I find the NEC support requirements for Flexible connection fittings ???????????????????????????????????????????????

If we are discussing hazardous locations only - Section(s) 501.140(B)(3)&(4). Otherwise, the requirements for "ordinary" locations hold and depend on the applicable wiring method.

I am referring to the flexible coupling raceway. Horseco.....

You have set up a chain of requirements beginning with Sections 501.10(A)(2) or (B)(2) with emphasis on the necessity rather than the convenience of a flexible connection. Then Section 300.11 plus the securing/supporting requirements of the rest of the associated wiring method such as RMC or IMC (usually Section 3xx.30) are applied along with Section(s) 501.140(B)(3)&(4). The general emphasis beyond securing/supporting the flexible coupling as part of the overall wiring method is avoiding stress on the connections/terminations.
