I remember being in my senior year of college, and I was rounding out my bachelor’s in mechanical engineering. I’d worked as an HVAC technician overnight to help pay for school, so I had plenty of on the job training to compliment my formal education. Prior to graduation, one of my friends from my old neighborhood reached out to me, asking for help in building a DIY refrigerator. He’d explained how he attempted to build it for a class project, but grossly underestimated the know-how needed to put it together. I laughed, asking if he managed to shock himself, and he said he nearly set fire to his kitchen trying to test it out! Laughing harder, I told him I’d come by later in the evening to help him put it together. When I got there, he showed me how far he’d got, and I couldn’t help but grin. While he assembled the condenser and refrigerant coils correctly, he wired the machine in a way that pulled full power from the power outlet! I shook my head, asking if he took the time to learn about electrical wiring before pursuing the project. He scratched his head, saying that was the point of the project. Oh man, this poor kid was doomed!
