I live in Pakistan and we have no electric panel or separate wires for different devices. I am going to rewire my house but before that I wanted to secure the refrigerator wire. I've been reading everywhere that there should be a 20A circuit breaker for the dedicated refrigerator line so I went to an electrical shop and asked him to give me a 20A breaker for it. He said that 20A is too high and I should get a 4A circuit breaker for it. We have a 220-240 single phase coming to our house. My refrigerator's nominal current is 1.25A with 200W. The circuit wire is 7/0.29. I tried to object saying the breaker would keep tripping because its a big one but he said that he has been using the same breaker for his own big size regrigerator so it will work. Eventually I ended up buying it and attaching the regrigerator phase wire with it. Its been 3 days but still it hasn't tripped. So I want to know is it safe with this amp breaker? Why do we need a 20Amp breaker for it when 4Amp is working just fine?
