Re: Where to isolate on large loops and wye

Charles Cauble

Thanks to all for your help.  I’ve been busy laying track. I also have a PM42 with breakout board to split my layout into 3 or 4 districts.  In the instructions it says the third wire should be a ground wire to a booster.  Since my command station is a 5amp NCE the booster is built in. I don’t know where I should ground it.  It mentions the third wire and Digitrax system. Is it  not needed with NCE?
