Hello all, new here and looking for a bit of advice on an old fuse sub panel I have.. So I have an old well house in my back yard that the structure is in good shape but the well is no longer is in use. I am planning to cap off the well and use the building as garden storage and what not. The building has an old fuse sub panel that I would like to replace. My question is what type/size of panel would I need to replace it? The panel says 30 amp but there are two fuses inside one is a 30 and one is 20. I'm not too familiar with panel sizing lol :/.. thanks in advance!
