richhotrainAs it turned out, the EB1’s were programmed to detect a higher current, so the main booster tripped before the EB1's could react to the short.
You can -- and if interested, should -- read all about it in the System Short Thread 2.
Brian, shame on you for not reading more of this thread.
The thread got too long so the OP started a new thread.

NCE tested the EB1’s and all were good. As it turned out, the EB1’s were programmed to detect a higher current, so the main booster tripped before the EB1's could react to the short.

What ever happened to this subject? What did NCE have to say??
I'm getting ready to make a choice of circuit breakers,...and a choice between EB1 or PSX

bearmanHey, Gary, this thread is getting to be really long, can you start a new one?
Maybe like "waiting for results" or something along that line?
Gary, I have a question that I have been pondering over when this thread was starting getting hot and heavy into the "what happened?" phase.
I read, a few pages back, that you originally wired this layout for DC. If that's true, would you mind explaining how you did it? Did you devide it into "blocks"?, and if you did, did you only gap one rail to seperate the blocks? By the way, if you did it this way, the rail without the gaps is the "common rail" you asked about.
And if you did all of this, what did you do to the wiring when you switched over to DCC?
I'm just really curious about all of this. I'll be waiting along with the rest of you for the info from NCE.

Oh boy. Hey, Gary, this thread is getting to be really long, can you start a new one?
Bear "It's all about having fun."
No, they haven’t even looked at them yet. Looks like it will be at least 6 weeks before they do.
Gary, so they were shorted out? But there is no why or how?
Just got off the phone with NEC. My tracking number tells me the breakers go there 3 days ago. The Tech support guy unceremoniously told me they are at least 6 weeks before they will get to my repair.
I asked if they were short handed or if there were that many problems that they just cant keep up.
He said it was the busy season
If that is the case, and any possible wiring issues are resolved, then hook up whatever circuit breakers you get after you hear from NCE.
rrinker It's entirely possible that the damage to the EB-1s happened back when you had other wiring issues, since resolved, but by then it was already too late for the EBs. --Randy

I guess I missed that it was tried in all 3 districts. Your threads are too long, that's my story and I'm sticking to it.

BigDaddy Seems to me NCE's response only leads down one pathway. A) The EB-1's check out fine and work in our shop, there must be something wrong with your wiring B) The EB-1's are busted; we've never had anyone burn up four breakers before, what have you done to the wiring?

From all our testing so far, the wiring is good. I have one EB1 that works on each district individually as well as connected to each district and the other two connected to the booster. Continuity and voltage tests show no cross wiring.
PS: the fourth EB1 was one I had that I thought was good but when we hooked it up it was not.
bearman In all my years on this website, this is going to go down as the most famous thread.

BigDaddy We know you had yard feeders that went to the main bus. If you hadn't fixed those, what would be happening differently right now? You short the main, the EB does it's thing and cuts off power to the main and the errant feeder. The yards still have plenty of feeders so they still work. The controller doesn't shut down because the EB is working properly We don't know why the 4 EB's went udders up and I don't think NCE will be able to tell you. It could be a coincidence, but I don't believe in coincidences.

Henry, I can’t rmember if I posted this or if it was a conversation with Rich but the feeders I thought were connected to teh mainline bus were not. Unfortunately, between my mobility issues and eyesite I took a quick look where both the Main and Yard busses cross and it appeared that the feeders were connected to the wrong bus. As it turns out they are mainline feeders connected to the mainline bus at a point where there is only inches between 3 mainlines and 2 yard tracks. My mistake.
How do we explain the EB1 working on the main line? It also works on the other two districts. Of course it is hooked up to only one district at a time while the other two are connected directly to thr booster.
I would not hook up any new circuit breakers unless and until you are sure that the wiring is bullet proof.
Has this situation aged you that much, Gary?
Just had a chance to send them Thursday. Now the wait....
gdelmoro richhotrain gdelmoro Can’t go up and down stairs again right now. I’ll do it as soon as I can. May be in the AM. OK, sounds good. If you reconnect the yards to the booster and short the Main, the EB1 should shut down the Main but leave the yards powered as long as there are no crossed feeders between the Main bus and the yard(s) feeders. Rich Yes that is exactly what happens. With the two yards connected directly to the booster and the main through the EB1 a short on the main Tripp’s the EB1 - Booster remains on - EB1 starts flashing as long as I leave the short in place. Remove the short - EB1 resets LED solid

Now, you just have to wait to hear from NCE.
And YES both yards have power and I can run locomotives.
I'll bet NCE gets lots of breakers returned that function normally but were installed improperly, so that was a canned answer.
Just for grins I am looking at a suitcase connector that I need to get rid of on a turntable I bought. How do you pry that little bar up without imbeding a sharp object in your non dominant hand?
