Kinda stupid silly question but no great on the electronic so just want to check..
But, going by these plugs provided with the board, 14 AWG (gauge) is what is expected to be used with power in and out to the bed?
The gauge of wire should be appropriate to the current that the bed heater draws (to prevent the cable overheating) and the length of the cable (so that you don't have too much voltage drop in the cable). So it's hard to generalise.
Having said that, 14AWG is rated at approx. 24A single core or 15A 2 or 3 core, and has a resistance of 8.5 milliohms per metre. So it's an appropriate choice for many 3D printers.
