There isn't much wire gauge variation available online, so I made one here. Easier to carry, and save places in toolbox

Wire gauge refers to the physical size and current carrying capacity of the wire. A larger gauge number handle less current. 

For example: 

  • 14AWG for a heated bed (12v @ 10 amps = 120 watts)
  • 18AWG for the hot end ([email protected] = 40 watt heater) 
  • 22AWG for the steppers and thermistors

Before measuring the wire, please remove the plastic coating around it. Twist the copper wire into cylinder shape, then slide the exposed copper wire into any SLOT on the gauge. Continue doing so until you find a tight fit. The number next to the slot will state what size it is.
