Planning on putting in some wiring runs from my Control Centre to various tracks, including a run of about 10m.
Wire Size and Feeder Spacing suggests that for G scale I should be looking at 10-8 AWG wire (6-10 mm2). This feels very big to me. For comparison, power outlets in Australia typically use 2.5mm2 wire to carry 240 V / 15A. I know that the G scale wires are handling 8 kHz, but much less power (approx 24V / 6A).
The LGB standard power connector is twin wires at about 20 AWG (0.5mm2).
What is a sensible wire size for a 10m core run?
