In this video we explain how to select motor starter and cable size selection and motor full load current calculation

In motor starter we explain contactor, over load relay, mcb selection

For cable we explain copper and aluminum cable
Copper cable take 6amp in 1sq mm
And aluminum cable take 4amp in 1sq mm

And contactor and mcb we take 50℅ more of full load current

And for over load relay we take 20%less &20%more of full load current
