DCC Boosters can Problem is, if you have a short on the layout and just rely on the main controller's circuit protection, the whole layout can trip and everything grinds to a halt. Good power management around the layout is essential. Circuit Most decoders will give short circuit protection of 1amp for a very brief period, so thought it best to use bulbs which would limit the current to less than this. Tony’s Train Exchange is your number one source for model train circuit breakers and auto reversers!
