Reply to "How much does voltage drop affect TNCC"

The issue with model trains vs. 120V wiring is voltage drop, not ampacity. If you drop three volts in a run to an outlet for 120V wiring, no big loss. However, if you drop three volts from your 18V supply, you've cut your track voltage significantly. That's the reasoning behind larger gauge wiring for model trains.
