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! |
