We do this for a living. Do you know how many times a customer reset the breaker and it started working perfectly again? 1 out of 10, usually due to brownouts. Do you know how many times they called me back two days later saying it was broke again? 9 out of 10. Do not reset a tripped breaker until a professional looks at it. You’ll usually do more damage to a unit. Like burning holes in refrigerant lines where your wiring shorted due to vibration and lack of tie wraps. Like burning your compressor up due to a bad capacitor. Like setting your entire electrical compartment on fire. Like blowing the compressor terminal out the side of the compressor, catching the oil on fire ? flames shooting from fan outlet. Like turning your electric heat elements bright and molten, dripping down inside your crossover flex duct, catching it on fire. Like turning a 10 ga Romex wire bright red, in crawl space going to a shorted compressor where the cheap guy or DIY’er installed an oversized 60A breaker. There’s many more. Don’t reset a breaker unless you’re sure it was a brownout condition. If you have more than one brown out a year and I would advise getting someone to install brown out protection on your unit, then you won’t have to worry about tripped breakers. Also, don’t install one big system because it’s cheaper. Install two separate smaller systems. Then you’ll have redundancy in the middle of the night when one heat pump quits working.
