Really don't know how to put this so you can understand it clearly but here goes. During my research I was told that I could take two single pole breakers and change to a double pole to save space in the main panel. I was also lead to believe that a double pole breaker has to be the same amp for both connections. In my main box it looks like I have four breakers (ganged) connected as one and the two middle ones are 40 amp and on each end are 20 amp. It is marked on the panel cover as the range. I have not pulled it out yet but it looks like one. Is this special for a range am I seeing things? I am trying to make room for a 60amp breaker and unless I am mistaken a 60amp takes two connection post. Sorry if I am not using the correct terminology but I am not an electrician so this is the best I can do.
