Irving said: I think you may be misunderstanding the meaning - the 5.6A starting current isn't inrush in the sense of a transformer etc. Its the maximum torque it can overcome from stationary and needs 5.6A to do so. If your inertial load is much smaller it will require less starting current. sussex road pharmacy gorleston
