Getting things mixed up electrical wise is not hard to do. I’ve done it. More times than I can count. That’s why at work, we have a guy who’s not very mechanical inclined and his mechanical design skills lack, where as his electrical understanding and design skills are the best of the team. So him and I have an agreement, he handles the electrical stuff and I handle the mechanical and when we get time, we try and cross train each other. Pretty good system so far.
