Fuse size for Closure Rails

You can figure this out for yourself. How much current does the locomotive draw, when running at an average speed? That would seem to be the amount you should provide via a fuse. Add an amp or two for headroom, if it's dragging a long train.

George,

This is the first time I've heard of anyone fusing the wire to the closure rail.  I assume the fuse is between the DZ-1008 and the rail.  Can I ask why you are doing that?

The wires off the DZ-1008 to the closure rails are pretty small, but they seem to handle all my scale engines without problems.  Of my engines, the engine that pulled the most amps under load was a Weaver diesel; it pulled nearly 4 amps before I replaced the electronics.  I would think you would need at least a 5 amp fuse in this application to not have problems.  Always fast blow.

Thanks Ron...I read somewhere or saw in a schematic that the closure rails should be fused...so I did. I took your suggestion and put in a 5A fast-blo fuse. Fixed my problem. Now on to the next one...
