Caution: You showed the handcrafted illegal male to male 120 cord. Good point. But you failed to show the 220 cord and pictures of the wall outlet configuration. Everything is very clear here but you start out showing a very common failure point using 120 but then show no step focusing on the 220 cord connections. What is hidden is how the 220 plugs to the outside wall outlet.
