Electricians

I sold my hot tub 😢. We ended up just decoupling this conduit and cutting the line. I’d like some advice on the best way to simply cap these off in a way that doesn’t become a problem later when I move out.

Not an electrician, just hoping somebody is nice enough to help out.

The electrician who installed it basically “stole” the connection that goes to the garage to install this. I’m still not exactly sure what he did behind that box, but I think I’ll have to figure that one out later.

Any help appreciated!
