Reply to "Wire size for 12v LED-accessory bus line"

KarlDLOGR Forum Member DIGITAL SUBSCRIBER

#18 AWG is sufficient if you are only powering LED lighting. Otherwise, larger wires are appropriate. On our Club's S and O gauge travel layouts #14 AWG is used for the 10V and 14V accessory buses. Don't use the track common (outer rail wiring) for the accessory return - run a dedicated one with the 10V.
