Yet another Beaver resurection (TC20F)
hermetic:
Is the breaker RCD? could be a bit of earth leakage rather than overcurrent, 65A does seem massive draw for the light loading!
awemawson:
Instantaneous starting current on mine, which probably has a similar sized spindle motor, is over 100 amps. Needs a type C at least, but preferably a type D breaker.
(My spindle motor is a 27.5 kW Mawdsley DC motor with an appropriately large KTK-Mentor drive )
JeffK:
Its a 63A type C Schneider circuit breaker (not RCD) which I expected to do the job. Obviously not. I guess I should upgrade....
hermetic:
Thats one hell of an inrush current!

I quite agree.
My lathe only has a 1.1 kW motor and it wouldn't notice a 10mm cut in nylon or acetal never mind a 1mm cut!
