Hi,
We know we need a 22kw motor to drive a centrifugal pump. This will be controlled by a vsd. My question is at this preliminary stage can we say that as the motor load will be approximately 42A, can we say that the vsd will also draw 42A and use this value to size the incoming cable to the vsd? Or do we work on the side of caution and say the drive will be the next size up (30kw) and use this to size the incoming cable?
Thanks
