NCE DCC EB1 Circuit Breakers
Tom Grassi
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 Allan Gartner Wiring for DCC

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.

Hello
I was able to get my EB1's setup and working. The track isolation took a little work and I had to replace some pieces of track the Dremel tools cut the rails no problem but on small pieces of track it tore it off the ties. Since I had to replace the track I used isolated rail joiners. couple of the larger sections of track worked well. The EB1 that was shorting or open was a wiring problem. I had to flip the two wires on the buss line at the EB1 connection polarity was wrong. Thanks again for all the responses. Tom -- Tom Grassi trgrassijr@...
