    Input mains power supply? (What are you running)

    I mostly just read on here,
    I've started collecting parts for my build mechanically I have my head round it all,
    But electrically my main supply I'm struggling with,
    Being in the UK we have 220v 13amp supply in the house, I'm thinking this won't be enough to run a 2.2kw spindle/VFD inverter, my pc, main power supply for the steppers and a coolant setup.
    Maybe I'll need to separate it out and split it between two sockets?

    How is every one else doing it?

    Also when I look at 2.2kw inverters single phase to 3 phase most advice an input current of between 16-20amps ? How are people running them on no mal feeds?

    Many thanks

    Gary

    2.2kw (9amps) is under worst case scenario, what FLA current does the motor plate show?
    You could always try it and see if you get nuisance blowing of the fuse.

    Hi,
    Not having any problems at all running a similar setup on 240v from 10A socket.
    PC / Stepper Driver / 2.2KW spindle / VFD / Water cooling. Drill press and grinder are also on the same circuit and haven't popped a breaker yet.
