Nicole:
Not sure if anyone has asked this. I am getting ready to start wiring my layout. I will have two independent main lines. One powered through a TPC400 and powered through the new Legacy powermaster (I run Legacy only). Both have separate power supplies - the powermaster has a 180 watt brick and the TPC has both taps on a Z4000.
My question/questions is this:
A ground wire is supposed to be connected between the Legacy command base and the TPC (Lionel video) or the command base and track (TPC manual). Since I have separate power supplies, track power controllers and electrically isolated track loops do I need two ground wires from the Legacy command base one to the TPC and one to the powermaster or to both track loops?
If this helps the track loops will be isolated by the power rail - ground will be connected. Power supplies will be phased (connected to the same wall plug so I hope so!).
Would there be any reason to have separate power AND ground rails and if so does your answer to above change?
Thanks Nicole
I appreciate
Joe
