I am planning to control a 1.75HP water pump using Arduino for automatic tank pump project. I bought a 12V 30A relay for that. Initially I thought that the relay with flyback diode, optocoupler and some transistor to control it. After googling for a while, I saw that a snubber circuit was also need…

Snubber circuit design for 30A relay.
