We have an old original subpanel located (ridiculously) in the second floor bathroom 2’ from the sink in our 1937 Cape Cod style home.
Our upstairs has two bedrooms (sans overhead lights) and 1 bathroom. The upstairs only has two circuits (one for the bathroom lights and an outlet; one for the hallway light and the outlets for the two bedrooms), and they both run through this subpanel. There are no ground wires in the subpanel. Both circuits have 15 amp breakers in this subpanel like so:
Down at the main panel (located in the basement) the feeder comes from a 20A 2 pole breaker. The subpanel is flush-mounted in a true 2x4 wall—the other side of this wall is the upstairs hallway. I’m in the process of remodeling the hallway (the bathroom is next up), so I thought I’d flip the subpanel access around and face it into the hallway (and conceal it with a decorative [removable] wooden panel).
I can’t foresee ever trying to run more circuits out of a subpanel in this location. We would like to add overhead lights to both bedrooms (I know, so glamorous), but it would be no easy task to run wires directly from this subpanel location to the bedrooms. So I don’t see a need for a much larger subpanel—or a subpanel on the second floor at all. Am I missing something? So perhaps I could replace this subpanel with just a flush-mounted (plastic?) junction box with a blank cover facing the hallway, or is there some advantage to having a second floor subpanel? If there’s an advantage to a subpanel on the second floor then I’d replace the current subpanel with a very small modern subpanel. I’ve included some photos and a wiring diagram in case that tips anyone’s opinion. Many thanks everyone--I appreciate this community.
