Good electricians might understand the theory behind it, but average ones just need to meet code without wasting too much time or materials. And to do that they follow patterns that work, patterns they learn from good electricians (or engineers).
Also, as an outsider, it seems like modern electrical code is designed so electricians don’t need to use common sense. For better or worse…
But we do.
If you don’t have a working knowledge of your craft, how can you apply common sense?
As the generation that I’m from dies out, there goes the knowledge.
