Fuse / Breaker Mix
This mid-50's house has a mix of breakers and fuses. The main panel is all breakers and was installed in '97. There are four secondary fuse boxes in the basement with two fuses each. One feeds the garage, one feeds the furnace, one feeds the outdoor A/C compressor, and one I haven't figured out what it feeds yet.
(I fear the latter may feed the outdoor lights, which all appear to be connected via 2-wire conductor in underground conduit, ending in bulbs covered by glass globes. I'm worried whether this might present a safety hazard if they get wet.)
Is there any real gain to combining some of those fuse boxes into a new subpanel? Or, since it works as is, should I leave it alone?
