I typically size motors at 125% FLA, end of discussion. Then I came across this table which has values up to 200% for a continuous duty motor on a varying duty load. A cheaper 5 min rated motor with the same load would only require 110% conductors. This table seems to be 100% backwards and required larger conductors for smaller/worse motors. Can someone explain the thinking and if they ever use this table?
I have a couple of intermittent auger motors and can't understand why I would size them at 140% instead of the standard 125%. I've read the commentary and all I can find online and it hasn't helped. Thanks!
