Hello All,

I have recently moved in to my new house and have been wanting to build a cnc for the last few years but never had the room.
So now I have the room it is time to build one, now my question is how much power do I need to supply it as I am hearing mixed answers.

My electrician has told me that he will be able to supply me 32amps to my shed fine at a cost but he also said if i wanted only 16amps to the shed it would be a fraction of the cost.

My Build will be.

Huanyang Chinese VFD, 2.2kw spindle
Water pump
3 axis stepper motors NEMA 23 which will be upgraded at a later date 5 axis
then the computer to run it.

Also is there anything that has to be added to the power to the VFD to prevent noise, tell me if i am wrong but i read up on something the other day but was partly asleep.
