Mike CT posted:Along with C.W. largest fuse on my layout is 7.5 amps (Track circuits). Most accessories are 3 amps or less.
Note the fuse blocks upper left, (Track circuits). Right is accessory fuses.
The 6924 Atlas switch relay boards were rated at 8 amps/ track circuits (7.5amps). I still had trouble frying traces on the boards and later added 3 amp fuses to the track circuits of the boards, some boards with (2) circuits required two fuses.
Note the fuse/fuse blocks associated with each board.
Both PH135's and PH180's can be paralleled for additional track power. Pictured is parallel PH 135's about 15 amps before they will trip, PH 180's paralleled 20 amps. The Fort Pitt High Railers older Z 4000 had tripped so many times they eventually would not work. Both Z 4000 went back for repair. Not work = Would not open.
Both Silver boxes, Lionel TPC's (Track Power Controller)'s have 20 amp resets. I've never had one open.
Mike, that is a serious setup you got there. Do you have any pictures of the layout this runs? The wiring alone looks very tedious. I like it.
