I have two power districts and two PSX-1's. Unfortunately I am a little confused as to the right way of wiring the circuit breakers to the NCE PowerCab. The diagram shows two alternatives, which is is correct, assuming that at least one is correct.
Thanks for any help on this. Pretty basic I know, but electricity is not my strong suit.

Alternative B, unless the PSX has a "pass through" connection for the power input side or the input wires are both in the same connector on the PSX, in which case either one is correct.
You can use either of the diagrams you have pictured. Download the manual if needed.

Daisy chaining the PSX boards together would be a clean setup. Our club has them on separate buss lines fed from terminal strips. This has added a lot of wire where if we had daisy chained them the wiring would have been easier to follow.
For the Power Cab you have to set the trip limit with the jumpers on J6 correctly. If not the Power Cab will trip before the PSX does. Also if you have sound decoders and or lighted passenger cars the weak system boost will have to be set or it will not reset.

I started with nothing and still have most of it left!
Actually I have the manual, and, believe it or not, I was still a little confused. Since I have two districts, essentially a walk in "U" gapped in half, I want to go with Alternative B using terminal strips to feed two separate bus lines. On a huge club layout, I would not be surprised about the complexity of the wiring. Mine is no where near that complicated. I am aware of the J6 jumpers, and I will double check the weak system boost. I don't think that I will have to worry since I do not have sound decoders or passenger cars.
Either of these methods will work. They are both correct. You can use either method. I have used alternative A in my case as I have 3 PSX-1 next to each other (it also eliminates a terminal strip). I also have a PSX-AR "Daisy-chained" as you have shown. The connectors on that side of the board are designed to allow you to easily daisy-chain the PSx's as you have shown in alternative A.

The two diagrams are electrically equivalent, as the PSX units have the connectors set up to daisy-chain if you wish. I have a PSX-4, which is 4 PSXs on one board, although each is a complete circuit and there are no connections between them unless you use the connectors.
The first diagram is for those who mount their PSXs near each other, while the second is more appropriate for those who prefer to put them some distance apart, perhaps to have them closer to the power district they are protecting. But, the location of the PSX is a matter of personal preference and it may be done either way.
It takes an iron man to play with a toy iron horse.
As it turns out, I might have to go for Alternative A since the PSX's will probably have to be mounted fairly close.
