Quoted from arolden:Bumping this topic with a related question. There are a huge variety of 18 and 22 gauge wires in terms of number of conductors and their diameter. What are the specs on those most commonly used under the playfield? Or does it not matter as long as the gauge is the same?
I've used both UL1430 and UL1007 Hook Up Wire. The UL1007 is more flexible but the UL1430 insulation is more resistant to melting from the heat of a soldering iron.
