I'm partial to fuses myself. When I replaced the Federal Pacific ($%@^$) panel in my house a few years ago, I initially wanted to install a fusible panel. Due to the scarcity of them in my area, however, I could not find one of sufficient size, and I didn't want to cobble something together that looked like it had been added onto a dozen times, and went with Square D.
This is an interesting setup, nonetheless, with a lighting panel (with switches), other panels with a combination of plug fuses and cartridge fuse pullouts (one pullout appears to be missing...?). I think the nastiest thing in this picture is the J-box in the upper right corner
Does anyone know what kind of business (?) this was found in?
