Re: Wiring help needed

Using a circuit breaker like the PM42 is not generally necessary with a Digitrax Zephyr command station. The Zephyr was designed for smaller layouts with one or two operators in mind. The current output of the Zephyr is only 3 amps.
External circuit breakers are generally used to protect a layout where multiple operators are operating multiple trains where a short in one area would drastically effect a second or third operator operating trains in other areas of the layout.

Please be patient as I’m new to this. Are you saying that I need a digitrax pm42 ? I can purchase one.  Do I then wire from zephyr to pm 42 then to track bus ? Or 4 power lines to 4 different areas of track from pm 42

Generally you won't need to isolate most places.
Reverser loops are different animal.
That layout looks like there are no reverser sections.
On a layout that size, you might want to consider a Digitrax PM42 Quad Power Manager.
This would split up the layout, for electrical short protection.
