Legacy only. Have 2 main lines & 4 yards. Each line has it's own buss (Hot & Com) and PH180 brick to power it. Yards will be blocks w their own power supplies. All switches on the layout are Ross with DZ1,000's. I'd like to use a dedicated 12-14v?? power supply to supply power to all the switches. Plan to control switches via: DZ pushbutton at the facia, from a switch on the control panel, via LCS switch controller.
1) is an 18 ga buss w 22ga feeders ok
2) need transformer recommendations
New to wiring. Any help appreciated.
