ACH580-01 Multiple Rating Tables Manual Supplement

This manual supplement provides multiple rating tables for ABB ACH580-01 drives (R1 through R9 frame sizes) to allow input and output conductor sizing based on actual motor full-load current rather than the drive's maximum rated input current. It addresses NEC requirements for multi-motor systems, emergency drive substitutions, and undersized motor applications, with tables for 208-240 Vac and 380-480 Vac systems, including minimum wire size limitations for specific frame sizes.
