Wow, this could be a real bugger to find for the electrician… When the starting torque required is very close to the available rated starting torque of the motor…in otherwords the motor is available torque at selection was so close to the load requirements…and as soon as one drops this available torque for the motor […]

What does a star/delta starter do: Imagine a connected big hosepipe and the tap is opened – the full  pressure will be available(delta), but what if the pipe is stretched such that the diameter decreases and the pipe grows longer…its the same pipe just differently configured.(star).
