Re: new dcc HO layout

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.
