Fuses?

Curious about what people with tracks are running for fuses or if they even do.
- 1 - If you have just 1 fuse for the power supply, what amp rating fuse do you use in relation to the total amperage of the power supply?
- 2 - If you fuse each controller hookup, what amp rating fuse do you use for each lane in relation to the total amperage of the power supply?
Appreciate any and all comments.
Thanks,
GT

My 30 amp power supplies have built in short circuit protection so I don't use any and my 30 amp relays and #10 wires will carry the full 30 amps. Having said that fuses are a good idea. If you have DC battery supplies they are an absolute MUST. I have seen the high amp draw cars spike the meter at near 10 amps when starting so 10 amps will work for any normal car. Normal running draw is only .3-.6 amps and maybe 1 amp for the hot ones.

It's probably worth some research to get that fuse size right. Too low and it's a nuisance....too high could cost you some money. My power supply has built in short circuit protection as well (8a), but it's on the 110vac coming in. I've wondered if I should use a fuse on the DC side also. Or will the built in fuse suffice?? Now that I'm thinking about it I guess I need to do some research as well.

The one on the incoming or 110V side will not protect your track. You may have internal protection. I have dead shorted my supply and checked the amp output on the meter with no harm to the supply. I would NOT recommend this if you are not sure you have internal protection. I think a 10 amp 25 volt fast blow fuse will handle almost any situation with HO slot cars.

Appreciate all the good info guys! This helps. I run 7.5 amps at each controller station on my road coarse which has proved to be sufficient but wasn't clear on what might be required for a drag circuit. I'm mainly concerned about a direct short, so I think for now, I'll go with a 10 amp fuse and see how it goes. I'm pretty sure that'll do it ..... and if it don't, I'll report back  . Thanks again! |
