I learned today that my residential fridge and microwave breakers are on a separate panel for Inverter powered appliances. Looked frantically as fridge was off and the ice cream was thawing. This happened a few other times and the fridge came back on while I was looking for the breaker. This time, I found the breaker first, switched it off and back on. Never heard of a self resetting breaker before. The high tech stuff today may be getting to advanced for us less mechanically inclined folks.
