mrhmag.com - November 2011 - DCC Short management demo

[MrGepatt]

I use the lamp for to protect my 5 Amps. booster and Bachmann EZ Mate control from a short.. If you have a direct shortcircuit (as with the coin in the video) 16 Volts x 5 Amps = 80 Watts, twice a solder !!!!! The only problem is that under normal conditions, there is a small drop voltage in the lamp, but it is not significant.

Thanks for the info about the safety aspects. That's good to hear.

That very cool

Been running this way on my large HO Siskiyou Line layout for 11 years - never had a booster problem in that time.

The bulbs let 2.1 amps flow when there's a short. Is it safe to have a 5 amp booster be asked to deliver a 2.1 amp load? Sure it is - all it looks like is several more locos just came on line.

What's less safe is a sudden surge of 5 amps with no load through track and wheels - I've seen is ruin equipment.

Boosters stop with a short as a protection: current running for DCC can be significant. At first look, this looks like a way to override this protection: current keeps flowing even if there's a short. I understand why overriding this can be convenient, but is it safe?

Great information!
