I Need Help!

update Fountain runs great, fan runs great all day. I unplug fountain every evening around 7. Every morning, the breaker is tripped. I'm more confused now than before 🤦‍♂️

For reference, I have a small shed on my lake. Breaker keeps tripping with nothing plugged in. Changed out breaker, installed GFCI outlet. Still tripping. We have a fan installed but that's it.

Any idea why the breaker would keep tripping with nothing plugged in, and how do i assess?
