Re: new dcc HO layout

Edward Sargent

If I’m following this correctly but if you separate the layout into power districts 5 amps are plenty unless you plan on having 10 engine consists. I have seen 9 engine consists pulling 140 cars using PB5s. Also unless I’m miss understanding 2 boosters don’t give you 10 amps. Also the cases of the boosters need to be bonded together.

I'm not an NCE user, but here goes.  If you have two devices, each of which can provide 5 Amps to power your trains, you may not merge the DCS and DB booster outputs before splitting off to the various blocks.   You'll damage the booster or the command station, or both.  They need to be kept completely separate all the way to the rails; this is the same whether you're using NCE, or Digitrax.  It's the same as having two power amplifiers for your stereo - you can't just tie the outputs together and get twice as much wattage. 

As for the buzzer, what powers it?  Again, you should get in the habit of not wiring any energized item to your rails, so if you're going to use a buzzer to monitor for shorts, make sure you disconnect the DB/DCS before you start wiring.

Don thanks for the advice. Yes I purchased the PH-PRO-R it comes with the command station integrated with a 5 amp power station, UTP panel and cables. Additionally, I purchase a separate power supply for the pro cab.  I also purchased a separate PB-5 amp booster that will give me a total 10 amps so I can run up to 10 loco.


The wiring of the pro cab and pb5 is my next challenge. I'm thinking they can both go into a wire terminal that separates into power sections. Or does the pro cab power station daisy chain into the pb5 then to the wire terminal?  That's what I need to find out. 


I'm going to take your advice and leave the circuit breakers off for the time being.  I purchased a buzzer that I will use when installing the track. I understand it will buzz if I install a feeder wire wrong.  


I am so new to DCC but very excited about the challenges and rewards. I appreciate your input.
