Where does my liability stop? I would not have known this had it not been hooked up to a 20A breaker by mistake. There is also a single built in oven where the load is only 3.3KW and 20a breaker would be enough and that 20A breaker was for that oven ,not the cooktop.Part of my job when running feeders to the manufactured home is to test things out and thats how I found out because cooktop was hooked up to 20A breaker by mistake and it tripped after a few minuets.
