You can determine you overall CNC machine current consumption be adding your spindle power plus your CNC motion power and the power that your computer requires.

the formula to understand the current of each component is watts = volts x current, or W = V * I, or with some algebra, Current (I) = Watts (W) / Volts (V)

For example:

Spindle:
The 2.2 kW = 2200 watts and you can find the current by taking the input voltage of 220 volt and get the current using the above formula: 2200 W / 220 V = 10 A (Amps)

CNC motion electronics:
The power supply that comes with our machines is generally 8.8 A

Computer:
The computer that you use to control the CNC machine will have a specific wattage. Let's say the watts is 500: 500 W / 110 V = 4.5 A

Add them up: 10 A + 8.8 A + 4.5 A = 23.3 Amps

The wire that is connected to the spindle can be a simple extension cord, that you find at a local hardware store. However there is a missing wire that is required(ground) which will have to be the same amperage of the extension cord.

The parallel (printer cable) port is uses the computer as its main source of pulse trains to operate the motor driver directly. Parallel ports are a direct connection from the processor commonly referred to as GPIO pins (General Purpose I/O pins) and provides a convenient and powerful way to interface with the computer. The parallel breakout board is included in those kits only to condition those signals for use with the drivers.

The USB serves at the actual controller, sending the pulse trains, but the computer sends simple human readable instructions to the USB controller to tell the controller how to send pulses.

The non-technical differences that may serve as the most important information to you is that the parallel configurations allow for a wider variety of industry standard software that can be used to control the cnc machine. The USB that we offer requires the operator to use a software called Planet-CNC software which is a very well made and feature full cnc control software.

Since a 220V 2.2kW, or 2200W spindle will consume 9 to 10 amps at full torque:

2200W/220V = 10A
2200W/240V = 9.2A

then a 15 amp breaker would be suitable for this load.
