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…
Electricians just need to know how to follow the rules, they don’t need to understand the underlying physics. Engineers, on the other hand…
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.
