Why can't I put one/two breakers to the left?!
I have no idea if the pictures are labeled with the description correctly so basically there are Before and After photos. The before is the original install with a cable that leaves the box at the top right to a “sub panel”. The after is the removal of this cable because I believe it’s not to code (not connected correctly in the box).
The top metal bus bar stub allows a breaker to snap into the bus bar stub on the right and one on the left. The metal bus bar stub connector is large enough.
However, the bottom metal bus bar stub only allows a breaker to connect on the right side. But it has a notch on the left so that means a left breaker can't connect. The bottom two metal pieces are like this, so effectively I have two empty spaces that are no use because the breakers can not connect.
Also, special note, the two little circles up top allow me to connect mini (1/2) breakers. The bottom two metal bus bar stub pieces don't have these either.
The two bottom metal bus bar stubs have one-way-turn screws. I could take these out and put a new bus bar stub? Why would a panel be designed to leave out two full sized breakers on the bottom left?
So one thing to note, there was a 40 and 30 amp connected to these. Could the power from a dryer and stove melt or burn these bus bar stubs so someone installed a new one that was only one side? hmmm?
