I did a thing in my workshop
It's a very small room 1.5x2.5m and I am the only person going in there, so I went a bit crazy with the electrical work. For now I have a single phase going into the workshop, but I designed everything for three phase power. All I have to do is to just buy a 5 lead cable and run it through the house. I have used what I had laying around because I'm broke as hell. Previously I've had a single phase GFCI and a breaker on the bottom din rail, but since turning the breaker on and off everyday manually would break it pretty fast, I built this abomination. The red hanging wire goes to door switch I've installed and will use it for something I'm the future. Now the contactor disconnects and connects the circuit so it's better, plus now I could add an estop button which I wanted for a long time.
