I've got a 1/2HP motor connected to a VFD rated for 2.3A output current with built in overload protection features. According to NEC 430.124(A) I shouldn't need any secondary overload protection.

Being a 1/2HP motor I'd like to follow 430.22(G)(2) to use 18AWG wire between the motor and VFD but in this section it mentions using all sorts of different short-circuit/ground fault protection devices, class 20 overload protection, ect... I feel that that it's safe to use 18AWG but is this up to code? Do I need to verify something with the VFD to make sure this acceptable?
