1 Line and motor cable size is selected according to UL508C 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.
2 Earthing conductor size is determined by the maximum overcurrent device rating used ahead of the drive according to UL508C Table 6.4.
3 If power cubes or bypass are used, a UL recognized Class T fuse is recommended.
