Taking The Icc Masters Test Again Anyone Know Good Study Materials For Motro Calculations And Conductors

Annex D of the NEC has a few good examples to study from.

This is as basic as it gets:

Step 1: Find the FLC of motor using Article 430 tables.

Step 2: Find motor running overload protection per 430.32

Step 3: Find branch circuit conductor size per 430.22

Step 4: Find branch circuit overcurrent protection per 430.52

Step 5: Find motor feeder conductor size per 430.24

Step 6: Find feeder overcurrent protection per 430.62

What I did to prepare for these kind of questions is give myself some hypothetical situations and use the above formula to determine what size wire, overcurrent protection etc. After you do several of these it will be so simple you won't believe it.:smile:
Put tabs in the above articles for quick reference.
