Motor Calculations: FLC, Conductors, OCPD & Overloads
5:30
A single motor circuit isn't one calculation — it's three separate ones, each using a different starting number.
In this lesson: FLC from Table 430.250 (not the nameplate), conductor sizing at 125% of FLC, branch-circuit protection percentages by device type (Table 430.52), overload sizing using the actual NAMEPLATE current, why these two sources are never interchangeable, and feeder sizing for multiple motors on one circuit (430.24).
Based on the 2023 NEC (Article 430).
