There's a problem with your power grid, or wall supplies in your home? Or these are outside in some boxes and get struck by lightening?

What exactly is getting damaged?

What's connecting to them? Other circuits or motors, things connecting into the board.

Perhaps you need some UPS? Or review if you need better isolation?

Nuclei boards are not Humvees, their main purpose is prototyping in labs, bug duplication on standard board when custom board fails. -40 to 120 °C, waterproof, electrical overstress requires rugged implementation as it is beyond normal operating conditions. At least find the root cause.
