If I am installing in-line fuses between my z4000 transformers and the DCS components, where is the best place to install the in-line fuse?

What are you trying to protect?

I have allways heard that the Z4000 had enough protection that you didnt need to do that.

I put mine between the Z-4000 Transformer and the TIU. Fuses blow and therefore add a layer of protection. Much cheaper than repairing/replacing a TIU. Dave G.

 

Please look in The Scenery Sourcelist first.

Keep in mind that the smallest over current protection most likely will open (blow) first regardless of position in the circuit.   These fuses, (7.5amps max), were positioned between the Block Power controllers and the tracks on the power side of the circuit.  Commons are complete back to a common bar and the common side of the two transformers.

I am using 2 Post war ZW's and I have installed Fast Blow 10 amp fuse's between the transformers and the TIU and works great and blows really fast when I have any kind of short or derailment.

He anyone tried the polyfuses and if so where did you get them? They blow and reset without replacement.

I use Polyfuses, but not for this application.  I use the 3A ones between pickups on passenger cars or between the tender and locomotive to protect the wiring.  They open too slowly for me to trust them for protecting electronics.
