Notes
Line and motor cable size is selected according to UL 508C Table 40.3 for copper conductor rated 75 °C. Use only with copper wire rated 75 °C here.
Size requirements for other different wire types are defined in the National Electrical Code, ANSI/NFPA 70.
Earthing conductor size is determined by the maximum overcurrent device rating used ahead of the drive according to UL 508C Table 6.4.
If power cubes or bypass are used, a UL listed Class RK5, J, T or equivalent fuse is recommended.
FR0 is not available till June 2018.
