What wire size between voltage converter and VFD?

Please consult the advice of a professional electrician. The information provided below should always be confirmed by a professional electrician and you assume all risk involved when working with electricity which is potentially hazardous and lethal. Never work with instruments and wiring on live electricity. The wire gauge used between the spindle VFD and the wall socket, or voltage converter will be determined by the current consumption of the VFD. For example, if the spindle/vfd is rated for 2.2kW and the voltage input is 220V, then 2200W/220V = 10 amps. In this case, it's best to increase the gauge for a current flow to provide a safety factor and consider 15 amps rather than 10 amps. A wire gauge that is too small will cause overheating on the wire and possibly cause the insulation to melt and cause a short. A wire gauge of 14 (copper wire) for 15 amps would be adequate. Remember that the length of the wire is important. The longer the wire, the larger gauge is needed. It will be very short wires. Maybe 12" long. 14 AWG should be fine.
