Check for shared neutrals before rearranging any single pole breakers.

Hi All,
My main panel is rated 100 amps with 6 15A breakers, 2 20A, 1 30A, 1
50A. I've mapped it all out and found that some of the 15As have over
1500 watts on them (assuming 1.5 amps for each outlet)

The 50A used to power an electric stove, which has been removed. Any
reason I can't remove the 50A breaker and install 3 15As and
distribute the loads better? There's plenty of room in the box.
