RE: Safety: 28V DCC & 2 year olds

Which voltage do you not recommend Stan? 24 volts or 22? I've never seen a system that sources 27 volts to the rails.

A common misconception is that the input voltage to a DCC system or booster equals the output voltage. In my experience there is a 3-4 volt loss between a DC input and the DCC output voltage (of course measured properly with an RMS meter).

p.s. I have 23 actual volts on my rails. It can "tingle" but it's "safe".

p.p.s Article 411, enacted 1996 lists 30 volts or less, with a maximum peak voltage of 42.4 volts, current from any one low voltage circuit not to exceed 25 amps.

RE: Safety: 28V DCC & 2 year olds

Dan, the originator of the thread indicated DCC, so I've limited my comments to DCC.

I think you will find that ALL DCC boosters have a regulated/limited output, and I have not found a US-made DCC booster that puts out over 22 volts, and most have a lower maxiumum.

So even with a higher input voltage, the output to the rails would be under 22 volts.
