Hi,

Yes, I get why the capacitor is needed for starting and phase rotation.

I'm still not getting this question and answer though. What am I missing here?
Why is the given answer True, due to the need for capacitors on a 3Ø motor?
Perhaps this is a typo in the answer and the code should be 430.37, not .27.

Question:
"You need three over load units for a normal 3 phase AC motor."
True or False
Answer: "Yes 430.27"
Code
430.27 Capacitors with Motors. Where capacitors are installed in motor circuits, conductors shall comply with 460.8 and 460.9.

Code
460.8 Conductors.
(B) Overcurrent Protection. An overcurrent device shall be provided in each ungrounded conductor for each capacitor bank. The rating or setting of the overcurrent device shall be as low as practicable.
Exception: A separate overcurrent device shall not be required for a capacitor connected on the load side of a motor overload protective device.

Thanks,
Phil
