Alan:
Might even put a mirror down there so they can be seen while operating the layout.  8)  :D  :D

ON28:
Thanks to Alan for answering my questions! Your comments on soft start-up are interesting, and thanks for not scolding me for my non-logical cheap thinking: Save $50 on a circuit breaker while putting hundreds of dollars worth of motive power at hazard!

Also, I have seen one DCC user who added an uninterrupted power supply to avoid what he says could be damage to sensitive DCC components from power outages/spikes. What do you think?

Not a DCC user so cannot speak definitively but my initial reaction is won't do much. An outage should just turn everything off and power spikes will be seen only by the power supply so doesn't make it to anything DCC.

Thanks Alan,

I think you'll need to do an update blog post now that the Big Honkin Resistors are not actually needed.

Back to soft start and manufacturers not building that in, I wonder if that's because they never did before (even Ring didn't build this in) and perhaps Keep Alives have inrush current limiting built in these days (I haven't seen a commercial keep alive circuit diagram to confirm this). I rekon with the fancy microcontroller built in and the very long charge time that Ring's PBM does.
