Re: NCE DCC EB1 Circuit Breakers

Tom, there is a difference between a “short “ or short circuit that causes a circuit breaker to trip and a loco to stop, and an “open” that simply causes a loco to stop. Be sure to use the proper words.  In your case It sounds like you have an open connection or broken wire, etc. use a voltmeter to help find where and why you loose DCC track voltage. Shorts can be caused by miswiring of the left and right rails as a loco crosses an isolated boundary between sections. Look for voltage across the same rail isolating gaps. It should be minimal. If there is significant voltage there you have a voltage Mis-match in your wiring.

NCE DCC EB1 Circuit Breakers 
From: trgrassijr@...

Hello All 
New to this Group 
Hope all are safe and well.

I have a small layout and runs 3 trains at the same time.  Have 14 switches
Use Atlas code 83 track on my layout.
I use NCE Power Cab to control my trains.
sometimes a train would derail at a switch and that would short circuit my entire layout. 
So I decided to setup Districts on my layout I have three districts now and forth one in planned.

My layout was all tied together by switches as cross overs.  also have a double cross over on district 2 and 3  

So I had to isolate the track on district 1 from district 2 and 3   in doing that I ran into a few minor issues.  On District 1 I found I now had a dead section of track which worked fine before I isolated the track.
After many trouble shooting step I found I had a bad feeder wire on a piece of track before the dead section.  I think it was shorting in out somehow.  Replacing the wires will be done soon currently I disconnected them from my buss.

My buss is a 14 AWG stranded pair of speaker wire  

Now with the three districts I have three separate buss lines 

My problem now is on District 2 on a section of the track it short circuits and the train stops 

I have feeders before the section and after the section it is a dead spot not sure what to check

I tried to put my layout here but it would not let me.

Any one have any ideas what to check

Thanks

Tom

Hi Tom,

Can you upload a drawing of your layout to this groups files section?  Show where your problems are. I or someone else should then be able to help you.

Thank you

DB210 with DCC++ EX Command Station 
From: Blair

A friend recently purchased a Digitrax DB210 as someone told him he'd need one for his layout.

He's trying to figure out how to connect it to his DCC++EX base station.

Can he simply use the signals from his rails to feed the Loconet RailSync wires to the booster (he wouldn't need more than 5A, so the DCC++ rail outputs are otherwise unused)?  What about the 'ground' reference booster input?  I suspect that's not necessary as long as he's running just the one booster for the whole layout - unless he uses a PM42, obviously, or other Digitrax device that needs the reference.  Comments?
Blair
