How to Size a Motor using WOLF method
Published 2018-05-21
W = FLC x125%
OL = FLA x art 430.32 depending on the nameplate info
F = FLC x art 430.52 depending on type of fuse or breaker
To find the FLC you need to refer to the NEC in Article 430.247 - 430.250.
FLC - Full Load Current
FLA - Full load Amps

Love the video man, you did a great job explaining motors and made it a relatively easy process to understand. One question though, where did you get the under 100 amp rule use the 60 degree column for table 310.16 for wire sizing?
