I need some advice on providing fuse protection for my model railroad. I've installed a small main power control toggle switch in my control panel rated at 6 Amps @ 125 VAC which I think should be sufficient. As listed below, my three power supplies will draw 2.4 Amps total. The toggle switch matches the others in appearance used in the panel. It looks nice and I'd like to keep it if I can. If my toggle switch fails or one of my supply wires shorts on the 110 VAC side, will the household 15A breaker protect my house? For a margin of safety, can I add a simple fast-acting 5 Amp glass fuse as shown here? The railroad is a modestly-sized N Scale railroad that will use three power supplies: 1 - Kato Power Pack = 110 VAC / 0.8 Amp In, 13.5 DC / 1.5 Amp Out 2 - Power Supply 1 = 110 VAC / 0.8 Amp In, 12.0 DC / 3.0 Amp Out 3 - Power Supply 1 = 110 VAC / 0.8 Amp In, 12.0 DC / 3.0 Amp Out I'll try to remember to unplug the railroad when I'm not using it, but I'm worried about the hazard if I forget. Perhaps I'm worried about nothing or perhaps there's another way to handle this. Thanks y'all.
