Description
Atlas #318 is a 50-foot reel of 20 AWG stranded layout wire in yellow — high-visibility color useful for signal-circuit hot legs, individual switch-machine coil leads, or any wiring run you want to spot instantly during troubleshooting. General-purpose model-railroad wire for any scale.
How to use
- Yellow is widely used for one of the two switch-machine coil leads ("left coil" or "normal" position), with another color for the opposing coil.
- Also useful for signal-aspect circuits where each color denotes a specific aspect or block.
- 20 AWG handles DC, DCC, or 12-16V AC accessory current with margin.
- 50 ft reel — enough for several full switch-machine harness runs on a medium layout.
- Color-code consistently with the rest of the Atlas wire family: black/red track bus, green accessory return, yellow/blue switch coils.
