A few years ago, the small company (4 people) I was at relocated to a new space that was as-is so we had to do the custom build out for it ourselves. Two of us are hardcore DIY types, so we took on the build ourselves. Part of that required electrical work. We found an electrician that worked with us on the plans and permits, but then allowed us to do the work for the internal wiring to the panel before he ran the mains with the explicit understanding that if there was anything that did not meet specs, he would not connect mains until it was corrected. So we bent conduit, pulled/labeled wires, wired the breaker, then held our breath when he came back for inspection. It was very satisfying when the electrician said it was better work than 90% of his employees. I wish I could find the pics I took of how clean the breaker panel was. The bending of the conduit and measure 3 times cut once was fun and frustrating at the same time, and the decisions on which way to run based on which route needed the least amount of bending was challenging and fun. I definitely have a much deeper appreciation of what electricians go through. It also made it very clear why I did not pursue that kind of construction career path my dad took and did everything he could do to have me not follow those footsteps. To this day, I find myself looking at the conduit work in places and admiring the work more than your normal person
