How to calculate cable and cb/fuse sizes for motors

Farmboy
I haven't had to calculate cable and cb/fuse size(s) for single and 3 phase electric motors for some time now, but would like to do so as a matter of interest, so is there a contemporary reputable resource I can use that sets out how to do so (I could google/youtube it but don't know about their repute/accuracy)?


Thanks

    Ask the manufacturer, either of the motor, or the machine.


    Typically, the startup current is 6 x the running current, but you don't need to size the cable for that.
