some electricians wire always on outlets ground pin up and switched
ground pin down.

If I ever rewire completely each room will have its own breaker for
easy service, a couple breakers foir lighting circuits only plus
breakers for dedicated outlets like fridge.

I have the hodgepoge too As cicuits have gotten overloaded I add more
dedicatyed breakers........

still its a mess, worse the ductwork is in the way leading to messy
romex to avoid obstructions
