Totally get that feeling. Had a similar thing happen when my train got stuck once. Makes you see those little delays differently.

Yeah, @hugo_grant gets it... sims build the gut feeling you need.

Gotta disagree on the 4-inch being fine for everything, that's a one-way ticket to burning out small motors. The right tool for the job is a real thing.

Honestly, I never thought it mattered much until my own panel needed work. Seeing a messy one totally changed my mind, it's such a pain to deal with. Do you find most electricians take that kind of pride in it?

Oh man, tell me about it. I learned this the hard way and my knees sound like popcorn now. The regret is SO real.
