This is a bit more theoretical but I am confused as to how this may have happened. I own an electric stove that is plugged into one of those large 240V sockets on the wall. Yesterday when I switched on the oven the appliance completely shut off but did not trip the circuit breaker so no other devices around my kitchen switched off. In order to turn it on again I tried to reset the circuit breaker but that didn't work. Then someone suggested that I power off some of my AC's which consume about half a KW, I did and after I reset the circuit breaker once again sure enough, the stove turned on. Needless to say I was completely dumbfounded.
So question 1) why would only the stove itself switch off without tripping the circuit breaker? It is simply connected to the socket without any sort of surge protector. 2) Most importantly why would I need to unplug some of the other appliances in my house just to turn the stove on? this is what confused me the most. I thought things just scaled, I am sure the power grid can carry much bigger loads than whatever my house was consuming.
