well,couldnt you just use the blocks for DC as short circuit blocks for DCC? just leave all the switches ON or take the block switches out and wire it all as one bit bus with circuit breakers in between for isolation if a problem occurs.im no electrician (dont ask me how i know that :mrgreen

but i think DCC wiring is more straight forward than DC so it should be simpler.tell me if you dont understand this

. its kinda hard to explain the things that pop into my mind...--josh
EDIT:also tis site may help with wiring your layout.itll give you an idea on how DCC is wired.its quite simple in reality.
