Wire size for 12v LED-accessory bus line

BenLMaggiOGR Forum Member

All of the structures on my layout are powered with 12v LED lights that I install myself. They are operated at 10 volts from the DC output of a train transformer, which hopefully will prolong their life a bit. For bus lines that will need to run no more than 20 feet or so, is 18g copper wire sufficient?

Thanks.
