The Fuse Box is a long electrical box with a glass door at one end that requires a breach to open. Confirmed spawns include Ancient Fort on Blue Gate. Keep an eye out for it in other electrical or industrial areas across the map. The loot pool is as minimal as it gets: Rubber Parts and Wires. Both are common crafting materials you'll have no shortage of from faster, easier containers. There's nothing here that justifies the breach cost in most situations. It can also container just general electrical items and mechanical items. Do not expect any thing crazy, just mid crafting materials and recyclables at best. Skip it unless you're desperate. The breach animation costs time for some of the most available materials in the game. The container does not spawn in much places either. If you happen to have time to spare and one is directly in your path, fine, but the Fuse Box should be at the very bottom of your priority list. The Floor Cleaner at least has an interesting location. This is just a bad trade. No raider has ever received something gamechanging from such a measly container. Just skip it.
