Feb 5, 2020 at 1:38 | comment | added | Harper - Reinstate Monica | Answers which say "safety doesn't matter" and "ignore electrical codes" are not well-received on this stack. If you hang out awhile, you'll find out why. Most people consider codes arbitrary, unfair and unattainable until they work with them for awhile, and then discover they are wise, really improve safety, and are easy. | |

I believe you've done it and had it work sometimes, but that'll vary a lot based on the design of the motor. In particular, the capacitor is likely very undersized for 120V operation, so it may have trouble starting without a push. Take a look at the capacitor table here -- the values for 120V are 2-3x higher than 240V: inspectapedia.com/electric/Motor_Capacitor_Selection.php | |
