Wire Diameter For Wiring A Routed Track

Recommended Posts



I'm at the point of wiring up my track :D and was hoping for some advice on what size wire to use.


It is a 3 lane routed analogue track. Lane length of 20m. I run RTR cars like Scalextric, Ninco and Slot.it.


I've seen 12 and 14 AWG wiring mentioned which is 2 and 1.65mm diameter respectively. I've got some 2.5mm wire. Will that be OK to use?

The best cable to use is Automotive cable, it is more flexible, 10 amp/4mm having 16 stands.

It is available in small rolls so colour coding is easier.

It is more common to be sold by amp rating, 6 Amp will be fine for your track, but you may find that 10 Amp is more readily avaiable.

Check out Supercheap or Autobarn for.small rolls.

the cheapest way to get wire for your track is to buy a 20 metre extension cord from Bunnings, cut the plugs off and strip it. its colour coded and heaps cheaper than buying colour coded rolls.
