I would you like your thoughts to two different ways to do sub-districts using breakers. I will be using 12 or 14ga wire for the main busses.
Option 1: booster and breakers close together and bus from each breaker run up to 30’
Option 2: main bus run 30’ from booster and breakers break off of this at different points and run up to 20’ each.
Diagrams below for the visual learners like me.
Thanks for your thoughts.
Those are electrically the same. The so-called daisy chain connections from one breaker input to the next are actually just parallel power connections. True daisy chain connections imply some kind of power or signal change before handing power or signal off to the next user.
If you fed the output of breaker 1 to the input of breaker 2, that would be true daisy chaining. There are cases where you might want to do that, but I don’t remember why you might.
the club layout has 2 multi-track mainlines with reversing loops at each end. 8 blocks each, circuit breakers for each.
3 boosters and associates breaker are in panels with the booster us running across the top and knife switches connecting each circuit breaker to the bus.
it easier to check for shorts if all the breakers are on one panel
the knife switches allow disconnecting each breaker to help isolate faults. it’s also each to attach the RRampmeter to the knife switch blades to measure current in that block
the command-station is in a separate room with a PC running JMIR for programming decoders
