Two loops connected/insulate???

I have all 3 rails insulated in my crossovers, but I think you can just isolate the center rail, as your ground is common anyways. To run seamlessly, you'll need to have both handles on the Z4K set to 18V, and your dcs channels set to 'AON' (All on, its in the remote menu somewhere), as you'll wire one handle to fixed 1, and the other to fixed 2 on the TIU. If your TMCC is tethered through your TIU, then you just need to connect the TMCC U post to the ground post on Fixed 1 out and you'll have TMCC control over the whole layout.

Great response and I thank you.  I'll assume the Ross Ready turnouts will carry the power into the middle rail divergent up to the insulated pin......Thanks

Yes it should. You can check with an ohm meter to be sure. You appear to be making some good progress on your project Doctor.   

Keep in mind that the two loops if power by different transformer, the transformers need to be on the same phase.  With a volt meter, one lead on center rail next to the isolation pin and the other lead on the other side of the pin you should read 0 volts. If you read 36 volts there is a phasing problem.

I am going to use one side of a Z4000 for one loop and the other side of the Z-4000 for the second loop.  That should eliminate any phasing problems???  Yes???  Thanks for all the responses.

Yes, All the outputs of a Z-4000 should certainly be in phase.
