My answer to Is it possible to make use of micro controllers instead of using MCB and ELCB for protection in house?
Answer by Shaunak Agastya Vyas:
Yes, it is possible. What you can do is you can drop down the line voltage and current to microcontroller level, measure the quantities using ADC of microcontroller, set the threshold levels of trip and do the same job. If you use some kind of DIP switches, then you can make this threshold level programmable using the combination of the switches.
