This is outside my house (see pics below). Looks like incoming power goes to this panel (2nd pic) before it goes into the garage panel (for everything in the house). On this panel, it has the 50A air conditioning circuit and its 15A (thermostat, fan blower, etc for the AC?). And lt looks like there is only a slot for a slim breaker. What if I move the 15A wire to to 50A breaker to make room so that I can install a 50A 2 pole slim breaker so that I can run a 240V 50A circuit for my NEMA 14-50 right next to it Codes? I will have to turn on the AC full blast and measure the ampere of the 15A and 50A?
