I'in in Arizona but electricians from back East tell me that because of the humidity in the air (in the rest of the country), "technically" the "breakers" in the breaker box should be flipped off then on every 6 months because the contacts can corrode together or corrode and lose contact. Same thing happens to these switches. Also, two choices of switch at H.D., Chinese for 85cents and American made $2.85. Guess which ones most of us buy. I FINALLY LEARNED. As usual, great video.
The problem with your other motor is no doubt a capacitor. The switch on your clean out auger motor has been weakened over time and when the motor first starts up it will have a current surge across the switch contacts and poof it burns itself off. You should be using a 20 amp rated double pole single throw type rated switch. If you are not operating your electric motors on 240 volts you may want to consider it. Your current draw will be less and other benefits. Talk to your local electrician. 👍🇺🇸🙏🏽✌🏻😎
