Of course, yes. The type of drive does not matter, its based on motor HP.
Part X - Adjustable Speed Drive Systems in Art 430 is a good place to start, in particular 430.122 Conductors Minimum Size and Ampacity
Why would you think there would not be a minimum size?
Thank you - Is #14 min. size for motor wiring in code or more of an industry standard?If the 20 gauge wire is factory installed it's not your concern as long as this equipment is listed and approved. If it's not listed and approved that is another matter. #14 is minimum size for motor wiring
14ga is the minimum we can use IN THE FIELD, which is what the NEC is all about. FACTORY built and listed assemblies have their own standards. Under UL508A, INTERNAL Motor Branch Circuits under 5A can use 20ga wire. Field wiring under UL508A is still 14ga though, so it might be a stretch to call the wire from a control panel to a motor "internal". I know my UL inspector would not.Thank you - Is #14 min. size for motor wiring in code or more of an industry standard?
